I reccomend trying to make a housing arrangement with the baae exactly 4 squares off the ground. (3 air spaces then the base). It should be away from raised bits of land as well and have the general flying mob defences. The 3 spaces prevents Wraiths from getting in your house through the walls as they can't float about 3 feet, Wraiths can destroy your NPC in a heart beat.
