Freerin is a curious elf who is more interested in the collecting of spells than the application of them. She has very little patience for people or the worries of her race.
Freerin the Spell Collector is based off of Frieren of The Funeral Procession from Frieren: Beyond Journey's End. Unlike Frieren, Freerin is
not being tutored by a single great mage, but is instead self-teaching, and is not concerned with killing, maybe perhaps because of the lack of existential threat in Azeroth, but its hard to say why Frieren is so brutal, as so little is known about her life.
