Bonepicker's Tower
They say the old baron went mad.
They say he killed his lover.
They say those ruins where once stood his opulent castle are haunted.
Most people avoid the Broken Tower high on Eagle Peak¸ haunted or not. Bad things have happened up there.
But some winged demon has been terrorizing Glynn Rock and something has to be done. They say the demon has been seen roosting on the crumbling crenellations of the Mad Baron's Tower.
And then there's the bones...
