Thaven

Thaven was likely a high ranking thaumaturge who discovered a number of entrances to the underworld. After briefly exploring one different from that of the one in Exanima, he theorized about the presence of what he named the Spellgiver which enabled thaumaturges to use their powers to a greater degree than usual. Hoping to find this Spellgiver and usher an Age of Thaumaturgy, he forcefully sends the thaumaturge Corlian to seek the root of magic by manipulating peasants to drive him out of his home. Corlian enters the dungeon after his apprentice Papin dies after probably agreeing to sacrifice himself to Corlian to be used as a subject for one of his necromantic experiments.

As Corlian descends deeper into the Underworld, he realises his body has not much longer left and decides to discover what he can after sending word to Thaven about what he has accomplished thus far. Thaven replies stating that he himself has made a significant amount of discoveries and promises to send someone to assist Corlian, likely the player when playing as UNKNOWN.
