Ioun

Ioun, the Knowing Mistress is the goddess of knowledge, prophecy, and skill. She opposes Vecna, who deals in dark secrets and hidden knowledge. As an NPC, Ioun is played by Matthew Mercer.

Symbols and Appearance
Ioun appears as an older woman of long, wavy silver hair. Her skin is weathered and wrinkled around her almond shaped eyes with purple irises. She wears blue and white robes that tumble out from her form in tendrils of parchment.

Ioun has a large, darkened gash of black, curling void in her stomach.

Tal'Dorei
Beneath the castle of Whitestone lies an ancient underground ziggurat, which was a temple to Ioun. Some 800 years ago, the land around that ziggurat was the site of a divine battle, in which Ioun and the god Pelor sought to banish the Chained Oblivion. Ioun was badly wounded in that battle, and Pelor blessed the land with his own Sun Tree to watch over and protect her hidden temple.

Issylra
Underneath the guild hall of the Slayer's Take in Vasselheim is another ziggurat, where Vanessa Cyndrial brings Vox Machina for their induction into the Take. The gynosphinx Osysa also resides within the walls of the temple.
