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 agathion.

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

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.
