Agathinon

Agathinon, the aasimon warriors, form the elite vanguard of the celestial armies. Agathinon are stern, serious, and unyielding -- devoted beings, unswerving in their constant pursuit of right. They only appear in their natural form on the Upper Planes. There, they look like Elves with opalescent, luminous skin and shining eyes. Elsewhere an agathinon assumes another form at will. They speak any language, using their powerful telepathic ability to do so.

In groups up to 100 strong, agathinon most often fight in Human form. In special circumstances, they transform into powerful creatures such as pegasi or dragons to do battle. Agathinon are fearless warriors who often defend their cause to the death. The Human form an agathinon uses nonedged weapons (for example, a sling or mace) and has formidable divine spellcasting ability. Agathinon never attack in their natural form. At any sign of danger, they assume another form, using the abilities of that form. All agathinon can become ethereal at will.

Agathinon sometimes carry out solo missions to the Prime Material Plane to aid mortals in their confrontations with evil. These instructions come down from the celestial stewards or, in the case of mortals of extreme courage and importance, from one of the powers themselves.

Rarely, an agathinon assumes the form of a magical inanimate object, usually carried by some other being: a magical lamp, sword, necklace, vase, or glass vial. In this form the agathinon confers all powers of the object on its possessor, plus other benefits.

Note: The agathinon originally appeared in this form in the Planescape Monstrous Compendium for the AD&D game from TSR. Their use here is for the purposes of providing context for the campaign only.
