Mirthshire is the 17th level in Dungeon Keeper. Mirthshire is a Tower Defense map. You must thwart incoming adventurers seeking battle and treasure. These parties are said to have "moved quickly to mobilise their forces against you" and do indeed start tunneling in just before the first Payday elapses. The objective is to kill or capture a certain Level 6 Lord of the Land leading the final party. __TOC__
