Tall Tales from Talland
Archmage Turen, Archmage Kayas, Archmage Siyera maintain the Senate's pocket dimension.
Turen had his head smashed in by a table in the Clockwork Factory by Mennas, but he had a clone of himself in the Senate pocket dimension. He accompanied Javel in evacuating people to the Warden colonies, before being captured. Geas and diplomacy convinced him to help against the Clockworks. He was killed in the last hour of battle by crossbow bolts.
