Background Volna is a Anti-Caster Specialist working for The Knights of Death. She usually works alone as a Bodyguard for a Non-Caster client to provide them protection from threatening Casters. She was infatuated with Thomas Riddleweaver but could never get up the courage to tell him. Once Thomas became a Lich though, Volna became very frightened of him and now She seriously desires to leave the KofD. She knows where one of the Keys for Thomas's Extradimentional Chest is and would be willing to tell PCs about it, Which book in it is his Diary/Phylactory and that Thomas is a Lich, of course.
