Death Types • Beheading


A vampire regenerating system cannot overcome or heal itself from a beheading.

Death Types • Electrocution

Same as fire.
Causes internal incineration versus external with fire but to the same result.

Fatal: this method will permanently kill a vampire if they are thoroughly electrocuted.
Their regenerating systems cannot heal from the overall damage.

Electrocution is the famous slaying method chosen by Cassidy's father, Tiernan O'Shea.
He levied it against so many vampires that it won him the moniker "Lightning".

Death Types • Fire/Incineration

Similar destructive pattern as silver, but quicker results.
Same as Electrocution, but outer incineration instead of internal damage to the organs.
Burns vary from painful to fatal.
Will eventually kill a vampire if they can't escape the flames in time for their body to heal.
Can leave existing scars dependent on the severity of the burns (e.g. Ames).


Ficlet: describes a short work that is written independent of the novels, for a specific purpose. It could be an alternate-version of a "favorite" scene, expand upon beloved characters and develop them off-screen, or explain something that crops up in the novel, but isn't explained there.


Ficlets are classified such if they fall within the canon of the novel itself. It needs to be within the timeline of events as seen in the novel, or the past-histories, and cannot reveal "canon" or "spoilers" from the future that haven't happened yet. Usually they tie to the novel plot in some way, and are just expanded on in short story form.

Garlic, Crosses, Holy Water

No effect on vampires, per Moonlight canon.
Vamps just really love rumors and misinformation like that.
When mortals come at them with stupid tools: real, survivalist vamps are only too happy to play along.


History: describes a work that tells the history (or backstory) of a character prior to their appearance in the novel.


An example history- how our protagonist began slaying vampires (and the crucial reasons why she chose this), when we jump into the fiction with the fact that she is a vampire slayer already established.

Human Blood / Food (Fuel)

From “freshies” is best, the younger the freshie the better the blood taste and stronger fuel for the vamp.
They can also taste different blood types (Lo told us this).

“Bottled” via Red Cross for the more humane type of vampire, who will buy bags of donated blood versus taking it off the living.
Mick St. John buys his from a vampire morgue attendant, straight off the morgue block, and just considers it his grocery bill.
(as we often term it in-universe "the Vegan vamp" drinks bottled, not fresh blood.)

Effects of subbing animal blood with human haven't been discussed or documented in our universe.


Interlude: describes a work that is "sandwiched" or appears in-between actual chapters of the novel to follow events going on off-screen and expand on them for the reader.


An example interlude- follows a character off-screen after the novel revealed an embarrassing paparazzi article, and shows the characters reactions to the aftermath. It's not essential to read the interludes to understand the chapters, but they can reveal more behind-the-scenes character development.

Mini Fic

Mini-fics are usually set in "present-day" without time or place, as just little sidebar-type stories.


Because they aren't definitely written to align with plot or any particular part of the novels, they may include spoilers, specific context in the moment they are written, or be set far in the future where the rules of the universe changed or progressed beyond the novel setting.

OC {Original Character}

OC or original character, defines a character that is not part of the fandom or universe but is created by a user or writer as their avatar.

OOC {Out of Character}

OOC, or "out of character", means to refer to something that is not

Regeneration vrs. Immutable State

Our Halflight canon stance is that vampires are ‘somewhat immutable’.

The vampire body can absorb changes but always tries to return to the state it was in post-turning.
(whether or not the body can regenerate or is prevented by some external source is key to their healing, and their immortality,
which is simply the body regenerating itself back to the "start point" . . . e.g. "turning").

Vampires can make small changes without consequences, such as restyling hair or shaving only on occasion
(original hair length and clean-shaven faces upon turning don't affect these changes).
But, with enough time & the natural regenerative process, a vampire body will regenerate anything the body determines it needs for species survival.
(e.g. torn fangs, several limbs, spinal damage and so forth)

The vampire body takes longer to run down than a mortal but ‘immortal’ isn’t a license to ‘maintenance-free’.
Requires regular sleep and fuel to keep the regenerative state in check.
Vampire bodies prefer a cool night habitat to daylight, indoors to outside and their genetic systems run to cold rather than heat.

Sleep Patterns

Vampires sleep in freezers or a custom cooling chamber (for those who can afford it)
In great need, or if they have to cool down in a hurry, they may improvise with a bathtub full of ice.
The freezer helps their self-healing bodies regenerate.

Modern equivalent to the “vampires sleeping in coffins” myth.
(before conventional refrigeration was available, a coffin buried deep in the cool earth overnight was the closest they could get to a natural freezer)

Strengths • "Leapy-Jumps" (weightless due to lack of bone marrow)

An interesting twist of the vampires altered genetics is what is termed the "leapy-jump".
Basically, its a vampire using their superior strength to leap into midair and they can do this at surprising and terrifying distances. (Seriously, Bengal tigers have nothing on a vamp going at full speed).

(Mick has leapt rather effortlessly from ground-level to rooftops, tall buildings several flights up, and even off the roof of a Los Angeles skyscraper. Heights seem to hold no fear for vampires due to their rather weightless state, versus humans).

This visually distinctive (and impressive) stunt is a combination of vampires accelerated hyper-abilities (in the speed and strength areas) and the way their physical bodies change at "turning". Vampires stop producing their own blood cells (thus the consumption of blood as fuel) and they also lose their natural bone marrow as it lessens over time. This makes them lighter in weight than mortals.

While its true that vampires cannot "fly" in the conventional sense of the word (either as bats or in human form), this stunt is pretty darn close!
Vampires can leap several flights straight up, though the actual power of the leap, height achieved and how much gravity factors in, seems to be unique to each vampire and his particular skill set.

(e.g. Mick clearly practices and performs leapy-jumps a LOT, therefore he achieves plenty of height and lift, and is impressive skilled at them. Contrast to Josef, who we only saw perform a leapy-jump once. He was rusty and nearly tripped.)

Strengths • (Vampire) Bats

Moonlight canon clearly states vampires CANNOT transmogrify (turn into bats, or any other creature).

But, if they ever figure out a way, Mick is first in line! 😄

Strengths • Continuous Regeneration of their Physical Body

Perhaps the greatest and most formidable of the vampire genetic transformations at turning is the body's ability to regenerate and "heal" itself.
It's actually through this genetic mutation that all the other abilities vampires are famous for emerge.
It gives them their immortality, hyper-abilities, lighter weight through lack of bone marrow, and healing instantly from injuries (much quicker than a mortal body).

(When Mick was shot on Moonlight, his body healed around the gun wound instantly, stopping the bleeding, though Mick had to cut the wound open again later to remove the bullet fragment from under his healed skin. His body instantly healed again, once he got the bullet out.)

The only threats posed to this amazing, Insta-healing, constantly regenerating system are vulnerabilities that are strong enough to pierce the vampire before he can heal himself from them.

Strengths • Heightened Senses

Vampires have heightened to off-the-charts senses.
Eyesight: with amazing night vision and perpareal vision. Even if they originally wore corrective lenses (Logan) the vampire corrects for this as a genetic adaption.
Hearing: (Mick can hear heartbeats, and a gun being cocked from 60 yards away. He can also hear a whispered conversation from some yards away and with background noise of a parade simultaneously.)
Smell: they can smell blood by type at great distances. They can smell poisons like tainted blood or vamp tea. Mick also claims to be able to smell other vampires out "by decay/age of the vampire in question".

(However, in compensation) "mortal"-taste is dulled (changed, after turning and the way that a vampire body processes fuel) to everything except blood and (some) liquids. Vampires can't really taste or digest mortal food, it doesn't nourish them properly anymore.

Strengths • Immortality

Vampires are immortal because of their constantly regenerating biological systems.
It isn't that they never "age" - it is simply that their body absorbs the "outer effects" of aging without transforming, as mortal bodies do.
They "heal themselves" genetically, the vampire body always tries to reset itself to the "start point" (e.g. the moment of their turning) so they don't appear to have aged at all.
While mortals are prone to death by breakdown of their bodies in "old age" - this poses no threat to a self-healing vampire.
There are, however, other threats that can damage their ability to self-heal and cause fatalities.

(for more on this, see Regeneration vrs. Immutable State)

Strengths • Super-Speed and Inhuman Strength

Vampires are inordinately strong and super-fast.
(We have witnessed, on Moonlight, Mick outrun a speeding car and pull the crushed door off a car after an accident. Both demonstrations of these hyper-abilities).
The hyper (or accelerated) abilities seem a byproduct of the vampires healing processes, where it supercharges their cells biologically, giving them faster responses synapetically, than mortals are able to manage.

Turning Signs

Eyes glow a silver color;
Fangs elongate and extend for feeding;
Pallor takes over face as all the blood drains away;
Transfigured face (it morphs and alters in an unearthly fashion)

Weakness • Dead Man's Blood

Toxic to a vampire on contact, whether internally ingested or externally absorbed thru the skin into the vampire’s bloodstream.
Effects of tainted blood (poison) vary based on deterioration/aging of the ‘dead blood’ in question.

Not ultimately fatal, usually the vampire will eventually flush the toxin out of their system (as it regenerates itself).
But, to a vampire, it has a similar outcome as a mortal with food poisoning.
If, for any reason, the vampire can't flush the tainted blood out of their system, it can however continue to do damage to their brain and internal systems.

Vampire can smell the rotten blood strongly though, so it has to be disguised in some way to infect them before they detect it.

Weakness • Silver Burns

Silver is very dangerous to vampires. It is currently unknown why this metal reacts so violently to the vampire but seems caused by some genetic anomaly that occurs at the point of turning, when a vampires base DNA mutates to their new living state.

Silver burns like pure acid upon skin contact, and is very painful.
Mortals can touch silver without harm, but it leaves scarring and raised red welts upon any contact with vampire skin.
It will instantly raise smoke and burn upon skin contact.
Vampires can smell the taint of silver and will avoid it at all costs!!

Ingested, silver is a slow-acting poison and will burn straight into a vampire esophagus.
Internal wounds can vary from merely painful to ultimately fatal.
In potent amounts (metal purity), and if not expelled from the vampires system, it is lethal.

Silver burns can leave behind scars if left untreated.
It takes significant amounts of blood for vampires to fully heal from silver.
Their healing systems are gravely diminished and don't kick in as quickly as they do with other injuries.

Silver is effective and one of the most painful ways to kill an incapacitated vampire.

Weakness • Sunshine (Daylight) Exposure

Weakens vampires considerably, will eventually prove fatal over a period of time (usually days) as the vampire system wears down with no food or healing to repair it.
Similar outcome to fire but not as fast-acting. It usually takes a few days for the sun exposure to overcome and weaken a vampire enough to kill it.
Can cause lasting scars/burns from the sun exposure if the vampire can't heal in time.
DOES cause a lack of control and extreme bloodlust on behalf of the vampire's need for survival.
A vampire will unconsciously attack any mortal prey nearby by raw instinct, as its body drives it with the instinct for fuel to self-heal.

Weakness • Vampire "Tea"

Results vary based on the herbs used, and the dosage administered, and the overall immune system of the vampire in question.
Can be used to cause sickness, paralysis & weakened strength.
Vampires metabolize at accelerated rates, so once the poisoned tea is administered, it takes effect near-immediately.
This vampire dispatchment method is known to be Cassidy's favorite, as she has historically used it multiple times.
Like tainted blood, it has to be disguised or the vampires can smell it out.

Not ultimately fatal.
Can affect vampire blood lust & libidos, as well as their defensive systems.

Weakness • Wooden Stakes

Causes total paralysis as long as the vampire is staked, but is non-lethal (not fatal).
Vampires have deliberately spread misinformation about wooden stakes as their form of protection.
As long as mortals believe a wooden stake will kill a vampire, the vampire can walk away from an negative encounter.
Cassidy herself falls for this fatal error early in her career.

However, a wood stake will incapacitate a vampire long enough for its prey to get away, thus its long-lived popularity.
The vampire revives and can move bodily again when the stake is removed.
