Ierin

"Sailing among the winds is the graceful form of Ierin. He swims through the sky like his mother before him, leaving strong tail winds and gentle summer breezes in his wake." -- Aicel Tales of the Gods

Ierin is the God of the Winds. He is flighty and can be easily swayed. He tends to be fearful of who is strongest. He takes the form of an Aarakocra  but his true form is a sky whale.
