Nyrissa was first seen in modern accounts by the Council of Redemere, while they were still establishing their charter in the The Stolen Lands. However, upon further research, she is akin to a deity & predates Ragnarok.
Nyrissa was found to be a former member of the Fae, having loved & been the most devout follower of Reynalk. Following Count Reynalk's granting of magic to mortals & their punishment from the Fae Court, Nyrissa was forced to raise & destroy 1000 civilizations, in apology to the Lantern King.
