This is information only the DM knows.
Kyrielle is not only a powerful mage (level 31) and incredibly powerful psionic (total strength of 1400), he is a very high level Frey priest (18). He wields a two-handed sword in combat, which gives off a light like him turning undead at all times, in a 20' radius.
His psionic power makes him essentially immune to lower level psionics, and he has every psionic power known at a very high level. He has also developed numerous psionic powers of his own.
