Triangle Tower is a daunting place to approach. Not much is known about its history, but there must be a fantastic story because of the variety of dangerous creatures that can be found there. On the top floor the masters of the tower can be found, a bizarre alliance of a Dwarf Geomancer, a Witch, and a Monk. To open triangle tower you use a switch in the desert. This switch is across the river from the tower, hidden beneath some rubble, here. It's a long walk to reach the switch, so you should check if the tower is open first. In case the tower is closed while you are inside, use the teleporter on the basement level to get out, but beware; there is a Bonelord down there as well.
