Tulani

Tulani were the most powerful type of celestial eladrin. They were peaceful by nature and rarely left Arborea (or Arvandor and the Gates of the Moon in other cosmology models).

Description
Tulani eladrin were beings of radiant grace and beauty that resembled stately elves. They typically wore shimmering robes of shifting colors. In their alternate form, they appeared as 8-foot-wide (2.4 meters) spheres of scintillating rainbow light.
