Duke Anders's Lair, evil ponies everywhere and a pack of Hyenas. A giant run down castle, with dangerous terrain. It is filled with many weapons and from the high towers Lord Anders and his followers are able to observe almost anything that happens in the Everfree Forest. Its entrance is guarded by troops consisting of different ponies and some hyenas, they are big and strong, but also extremely stupid; they are organized in way of military rank.
The castle is build in the center of Everfree Forest and is very well known around Equestria. It is considered Anders's stronghold, and despite Lord Anders's absolute disregard for the territory of other kingdoms most neighboring realms, seem happy enough to let Anders rule over the Everfree Castle.
However the six main ponies have occassionally entered the castle in order to stop one of Lord Anders's many schemes, this is also the place where Anders is most likely to take any unfortunate individual he seeks to imprison: the castle having many dungeon chambers by which to store said prisoners.
