Mad Fidalgo's Tower

This is a cursed, trapped, haunted, mage tower straight out of the Old World. It's original owner was on the cusp of eternal life, and accidenlty absorbed the life from his entire family and everyone he loved was immediately slain and raised as undead. His mind snapped and he tried to take his own life, but it is said that he instead became a lich that never admitted it to himself. This drove him mad, convincing himself that the area's paladins and clerics that came to combat him were actually the demons. In an attempt to purify these "demons" he tortured them and took their life and purified them into his army of undead. In life he was a great illusionist and his subconscious self would put the forms of his long-dead family members onto these twisted undead people of faith. So it has always been, so it is yet. Vast wealth and immesurable magic draws the greedy and pious alike. And all groups share the same fate.
