Celestials

Celestials are a form of Outsider which are defined by their direct subservience to a Deity, Domain, or other similar force or concept. They are often depicted as being Good, Lawful, or Honest, and are often associated as the enemies of Fiends... But none of these are necessarily true.

These Celestial Stereotypes come from the Angels, many of whom serve as the hands of deities often thought of as Good and Lawful both, but Angels are a very specific example. Far more Celestials serve as guardians, defenders, or warriors to their cause, including the majority of Angels.

Celestials are a specific type of Outsider, not a true type of creature on their own. Celestials specifically describe an Outsider which gains power through serving a Domain(Sometimes indirectly through a Deity). Thus, there are Celestials of Death, Angels of [Pick a deity], and so on, some Celestials being specific to a Domain(Kirin being tied to Nature, Lightning, Storms, and such, as a random example). Contrast to Fiends, which are Outsiders which gain power from consuming Souls. There is nothing exclusive between these, and as such you can have FIendish Celestials(Or Celestial Fiends, it's mostly a matter of preference). Non-Outsiders are sometimes given the "Celestial" or "Fiendish" monikers, but this does not make them Outsiders necessarily... It can be confusing.

Some types of Celestials are listed below;

Angels
The classic. Angels almost always serve a deity directly, and as such there are Angels for every domain and combination of divine purviews with unique quirks based on who they serve. Nearly all Angels are capable of shapeshifting, and as such choose to appear as people or animals whenever they interact with mortals, however their "true" forms are esoteric. Semi-famous examples of this include books bound in wheels and eyes, living objects lit on fire, and other such oddities.

Angels are separated into 'tiers' of Angel, the lowest being Devas, which serve as Messengers, and reaching upto the massively powerful, godlike Archangels. These get worshipped nearly as much as true deities and idols throughout existence, and as such bear true fragments of divine power. These archangels almost never find themselves in the employ of a deity, instead serving truly divine causes with their personal purviews.

Oh, and don't forget, some Angels are evil as fuck. Some of the nasty deities, death gods, monstrous freaks of power have angels in their employ. It's hard to tell the difference between them, with their shapeshifting. So if you see an Angel, start praying, and if you're lucky it'll hear you.

Agathion
Agathion are a rather interesting type of celestial, as they were created much in the same way many deities were, from mortal belief. More specifically, Agathion were made from the thoughts of "Guardian Angels" and more specifically "Guardian Animals". They resemble sentient animals, with their purviews being defined by their animalistic associations; Leonel are regal lion-like celestials, which serve such purviews as Nobility, Nature, and of course Lions. Which is a purview. Fuck you.

Asura
War-like celestials created directly through violence. That is, the emotions that come out through tragedy, mostly violent tragedy but also natural disasters and the like, are powerful enough to create the Asura. Their purviews tie to those that created their existence; Asura made after a massive storm would be tied to Nature and the Tempest, among other things, while an Asura made in the depths of a true war would be particularly War-like in domain.

Asura tend towards humanoid appearances, though they have a set of wings per distinct domain they carry within them. Unlike most celestials, Asura cannot typically shapeshift.

Archons
Archons are the only celestial which could be truly and commonly called "Evil," as Archons reflect the destructive aspects of their Domain. Archons only reflect a single domain, and as such are not as powerful as most other Celestials, but their powers are very dangerous and twisted. Their creation is debated; With the non-existence of a positive archetype to balance the effects of Archons, most claims of their existence being natural are dubious. I mean, all of their creation stories are dubious, but the idea that these things just exist because that's how the world is... It's a bit weird.

Archons' appearances vary massively, though many are humanoid-ish. These are usually bad news, but they don't typically work with other nasties aside from eachother.

Lillendi
Lillendi are a specific kind of Celestial, and are a sort of counterpart to Succubi and Erinyes. Lillendi are celestials tied to passion, beauty, and artwork. They are closely associated with Fey, as they get along quite well, and there are battles in Arcadia centered around the competing interests of Lillendi, Succubi, Erinyes, and other such creatures.

Lillendi are lamia-like, with wings and a snake-like body but otherwise humanoid make.
