*Castles101* This is a rough sketch of castles. Once you get to Journeyman Level 15, you can buy a castle. Castles are one of the most expensive things in the game. Simeon FireMane, or just Simeon, will help you. In every Housing Shop, except Grizzleheim, there is a turtle who sells houses. Before you buy a house, you can preview it, and Myrella Windspar will give you a tour. There are two houses, one big, one small, for every world, except GrizzleHeim, and now there is a house for every school! (Except for the possible Astral Magic classes) Each castle has an indoor and outdoor area. You can store roughly 250 furniture items in each. One corner of a castle is about the same size as a dorm room. There are multiple rooms and plenty space. Hope this helps!
Most of the benefits have to do with accessing areas. The least expensive house is the small house in Wizard City, and it costs 8,000 Gold. If you want to look at some of the other worlds' houses, we can meet in the game and I can take you to them.
