Threads of Invasion
Traevus was founf by the party in the ruins of Kalton Manor, in the Shadow Marches. He said he was seeking revenge on Anarus Kalton, a former colleague who killed their mutual master Malareth. Traevus believes that Anarus remains somewhere in Kalton Manor, undead, and is in possession of the Malarethi Codex.
After meeting with the party, he accompanied them into the heart of Kalton Manor, where he was killed in the big fight against a ghost and his skeletal minions.
