GeM is sent to Lord-Protector Jatim and Lady Savane so that they can GeM can gain access to the TTT source network.
Geraldine el-Mesir, former Countess of Ilien, arrived in Kiedel last season with a smallish entourage of bodyguards, servants and assistants. After paying her respects to Archduke Osoer she mostly hangs around the siege camp. In early autumn she makes a trip south, destination Mhowe. Once there Jatim will bind the sources of the Three Towers to her so that Geraldine may utilize her realm magic on behalf of the Crusade.
Once done the plan is to first cast Celestial Siege Train (something which she did to good effect during the Siege of Ilien).
