Harmonious choir of the words

Harmonious choirs of the words (often shortened to just harmonious choirs) were highly intelligent and powerful celestials.

Description
Harmonious choirs looked like balls of light some in diameter, with a smooth, not-quite-human face floating within and a stream of runes floating from the mouth. The coloring of the face and the runes varied from individual to individual, though most were of the cooler colors of blues, greens, and purples.

The voice of a harmonious choir sounded like dozens of voices speaking in perfect unity.

Personality
Harmonious choirs were friendly, voluble, and were more interested in promoting good than what structure or lack thereof underlay it.

They loved nothing so much as conversation and knowledge: to them, the wrestling of ideas, enjoyment of learning, and beauty of language were their own rewards; whether such occurred as conversations between peers or were given more as tutorials was secondary at best. They constantly sought out knowledge, however trivial, and gladly shared what they knew, though keeping one on track could be difficult.

Abilities
Harmonious choirs were creatures of powerful and potent magic as well as knowledge. They could, for example, dispel magically-induced silence at will, and they could innate bypass or dispel magical glyphs, runes symbols, and other writing, nor did they suffer negative effects from such writings if they did not choose to. Beyond that, they had a number of innate spell-like abilities, being able to replicate the effects of analyze dweomer, commune, daylight, detect thoughts, discern lies, enthrall, flare, legend lore, message, read magic, speak with dead, and stone tell all at will; dispel evil, dispel magic, glyph of warding, and major image each thrice per day; and erase, hold person, shatter, shout, suggestion, summon monster V, and teleport each once per day.

Combat
Harmonious choirs of the words were peaceful creatures by preference, but they did not shy away from combat to protect themselves or other. They typically targetted enemy spellcasters first using their own spells and spell-like abilities, as well as their ability to fire off rays of light that sapped both the physical strength and mental fortitude of foes.

Society
Harmonious choirs were said to be living embodiments of the Words of Creation, which were the words used to create everything at the beginning. Whatever the case, they were in fact made of many words that were, akin to a sentence or paragraph, arranged into a single structure.

Harmonious choirs were scholars that were constantly learning, talking, often singing, and sometimes even composing poetry. They were native to the House of Knowledge, and harmonious choirs would serve Deneir, Milil, Oghma, or, more rarely, Gond.

Accordingly with the natural talents and inclinations, harmonious choirs favored training as bards. They spoke all languages, but they themselves preferred the Celestial language.

Trivia
