In search of anything that might give them an edge against The Exiled, The Raven Shield meet with Koltis, the Dragonborn head archivist of the Unknown in Turtleback.
His lead about a powerful wizard on a secluded island mastering the power of teleportation transports them to a forgotten island and a fallen fortress.
Battling their way through the remnants of a failed siege of the castle and the animated remnants of defenders, the party faces down the wizard's animated spellbook and finally recovers the Staff of Edivius, before escaping the crumbling tunnels and teleporting back to Turtleback.
