The first mansion is called the Swamp Mansion. Even though it looks tumble-down on the outside the inside is fancy and extravagant and got a touch of mystery to it. The mystery part is actually existent in the house so you might want to look thoroughly through it to see what you can find.
The second mansion is the Hillside Mansion which both exterior and interior got a very majestic look to it. The front of the house overlooks a village with little houses and mines. The closeby area is also great for hunting.
