Ioun

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

Appearance
Ioun appears as an older woman with 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.

Personality
In the Campaign One scenes where she is encountered by Vox Machina, Ioun comes across as a rather kindly, and even rather tolerant deity. The one thing she is intolerant of (or perhaps impatient with) is the keeping of secrets and the hiding of knowledge. This is the reason given as to why she chose Scanlan as her champion rather than Percy, who to many seemed a more obvious choice. This is a bit ironic considering her own secretiveness about her presence and location, though such caution's necessity was made evident by her unhealed wound.

Symbols
Ioun is frequently represented in religious iconography by either a triple eye symbol (such as the one shown above right) or a unique eye-and-staff symbol, as shown to the immediate right.

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
The space underneath the guild hall of the Slayer's Take in Vasselheim holds 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.

Wildemount
The Knowing Mistress is one of the deities approved for worship within the Dwendalian Empire.
