General Glenaron gave up everything to stop the Beetle Queen's invasion. He lost his wife, his youth, and his innocence in a constant war that suddenly ends. His next cause is clear: Venture to the Cursed Valley and retire as a Warden Mage.
Unfortunately, the Cursed Valley is actually cursed, he has no gold, and politics plague him. The Dungeon Realms can help alleviate his burdens and aid in his goals. It'll mean starting over from Level 1 and learning a whole new system, but he'll do what needs to be done.
