Angel

Angels, also known as the aasimon, were celestials that hailed from any of the upper planes. Powerful entities of light and goodness, they were the traditional enemies of all manner of fiends and served as the warriors, stewards, and proxies of the divine powers.

While properly, the term "angel" referred to a subset of celestials, those on the Material Plane helped by any celestial being might claim to have been "visited by an angel".

Description
Angels possessed comely looks and what appeared to be wholly physical bodies, though this was an illusion. Angels all exhibited wings of some form, which they used to fly.

Abilities
All angels had a number of inherent magical powers, a large number of which could be utilized whenever they pleased. Scholars reported that they had the ability to grant divine aid, perform auguries, change their appearance, comprehend languages, cure serious wounds, detect evil or magic, discern moral and ethical alignments, read magic spells, and teleport without error. Angels were also said to have a special power over mortals to invoke reverence, by releasing a brief, blinding burst of light, which paralyzed mortal viewers with either love or fear.

Angels were resistant or immune to a number of energy types, including acid,  cold,   electricity,   and poison. Several were also immune to the effects of petrification or fire.

Although not all angels were capable of seeing through the darkness unhindered, many were.

Angels were generally capable of speaking the language of any creature they came across, even if they did not know it inherently.

Unlike other outsiders, angels could not automatically gate in or summon other angels to assist them. They had to rely on sending out a distress call, to which other celestials or good creatures might or might not respond.

Personality
The immense power of angels was balanced by their compassion and kindness.

All angels were honest beings, who found lying or cheating abhorrent. Likewise, it was against the nature of angels to steal from others, and angels were typically honorable and trustworthy in all their dealings.

Types
The angels were divided into two main groupings—warriors and celestial stewards. The warriors were called upon to fight for the good gods and to defend the borders of those deities' realms. Some sources held that angels were more likely to fight other angels from other good planes than fiends from the Lower Planes. The only commonly known type of angel to serve as warrior was the agathinon.

In contrast, the celestial stewards were those angels who served as the direct hands of the gods. Each type had a particular purpose to serve. From weakest to most powerful, the celestial stewards were:
 * Devas,
 * Lights,
 * Planetars, and
 * Solars

Creation & Ascendance
Angels were created by the will of their deities from the spirits of select petitioners. The gods or goddesses simply formed new bodies for these chosen followers in their afterlife, making them into agathinons.

Agathinons who served faithfully as warriors in the holy armies could be promoted and transformed into celestial stewards in a process called "ascendance". Such a promotion involved a change in physical form, magical power, and status. Typically, Agathinon were promoted into devas, who were in turn transformed into planetars and finally solars. The powers considered the good deeds performed by the angel when deciding when and how to promote him or her.

Fallen Angels
Although angels epitomized what it is to be good, they were not infallible and were still capable of corruption. In fact, in some cases, it was their strong sense of honor and refusal to lie or cheat that left them open to being corrupted or manipulated. Good intentions did not guarantee that an angel would always act in true righteousness, and sometimes an angel would fail in thinking that the greater good justified an action that would cause harm to an innocent.

Any such angels to commit an egregious deed of evil were noticed by their superiors immediately. Except for the most despicable evils, angels were usually given an opportunity to see the error of their ways and repent, but if they continued down the evil path. A celestial tribunal was gathered, with one of the god's proxies chosen to judge the erring angel and cast judgment. An advocate was chosen to reason with the offender and to petition the tribunal for a chance at redemption for the offender.

The punishment to an angel usually involved revoking of powers and/or descendance to a lower form in the angelic hierarchy, usually the form of an agathinon. An unrepentant angel was instead stripped of all powers and cast into the Lower Planes. These were the "fallen angels", and their names were never spoken in the Upper Planes again. The spirits of most fallen angels were consumed by the fiends with great pleasure; however, some were instead formed into the lowest of the demonic, daemonic, or devilish hierarchies to become fiends themselves. Some of these fallen angels eventually rose to become powerful fiends, ruling over legions of evil.

Society
Angels lived primarily in the Upper Planes and were permitted to travel freely among them from one to the other. They could also enter the Astral and Material Planes if directed by their divine masters, to support the purposes of good. Only very rarely were they ever sent to the Lower Planes and only for missions of upmost importance.

Especially good and powerful worshipers of an angel's deity sometimes attracted the notice of an angel if in dire circumstances.
