Fortress Kroth not only has a problem with Gresh the Seck Necromancer and his minions, but if you listen closely the solders in the fort will tell you about a dragon problem, they where having until Gresh showed up. The imps you encounter on the way to defeat the GOM, reappear in Legends of Aranna after you have gone down the lift where you place the town stones. These imps are an upgrade of the ones in Kingdom of Ehb, but their creation story and who made them are the same. I do believe you learn about the stone of the 10 legion near where you discover Kikra the imprisoned mage. Again you do not discover its use until the end of Legends of Aranna. Remember to listen and read - do not just kill.
