The Medievil Fortress is a stage in The King of Stories. It is not based on any particular location in any universe in the game. Mario, Kirby, Pit, Fox and Zoroark are playable here.
As its name states, the stage is like a medievil village, protected by a huge wall. The village is built next to a mountain side and features places such as castles, churches, shops and other various, typical, medievil places. The fortress seems to have been abandoned for a long time, as it is very dusty many of the towers and castles are ruined. Most of the buildings and roads are many of stone. The stage features multiple enemies.
