Tamnayal
Tamnayal is a human and Emile's teacher.
(Notes: Her possession of an albatross (See Albatross or Albatross (bird)) somehow seems to imply a forthcoming betrayal. She associates many of her own troubles with Kallisto. She also takes the Tome to Kallisto while Emile is masquerading fire (it is unclear if the Tome completes its journey She also struggles between keeping it and giving it to the LPC. She leaves the masquerade ball and isolates herself for a few hours (implied three hours), with there being some time presumably during which she is doing this for the purpose of isolation due to guilt rather than in the actual act of getting the Tome to Kallisto.)
Appearance
Tamnayal is a human woman [an age Ary/Peter would classify as "older," perhaps 50 or 60? Though is sometimes shipped with Connie, who is 25 years younger. This does not have to be the case but it occurred to me she might look younger due to technology or her own abilities]. Her hair length changes throughout the series.
Personality
Tamnayal (whether she is or isn't in reality) comes across as tortured.
Abilities
Early Life

The LPC then gave The Forgotten Tome to Tamnayal,
Tamnayal became engrossed in the Tome, sometimes neglecting to train Emile.

. . . Tamnayal then turns on Emile, [referencing Anastasia's art: She comes out of, or walks away from, a burning spaceship, though could be interpreted as other wreckage]
