Elissa

Elissa is the resident mage of Serpent's Fang, met by the Avatar during the quest to recover the Silver Seed. She appears to be a proficient magic-user, as well as a merchant (shes more than happy to sell the Avatar several spells for the price of gold coins. She also offeres the Avatar magical training for a price, which made her the only magical trainer in the game.

It has been speculated that Petra is the automaton reincarnation of Elissa, as they both appear very similar, although if this is the case, then Elissa has lost all memory of her former life during the War of Imbalance, and as such knows of no other life than Petra's.
