Senja Castle is located on the north-east side of the Ice Islands of Senja. It was once inhabited by Alawar, a perhaps evil sorcerer. There are five floors of the castle.
Alawar has his treasure locked away beneath the castle. It is guarded two ways: by mercenary Minotaurs from below, and a room of fire, poison, and energy fields from above.
Once in the treasure room, the teleports there take you to the roof of Senja Castle. There is a room below the room with fire, poison, and energy fields that contains two chests, which can be opened for a prize.
