Old Haven was born from the chaos of Rending. In those quaking days of old when the transcendent swept the sky and magic ran amok, the southern stretches of safety for men were being plunged to darkness. It was in the darkness however one found means to survive, to bring order to inhuman and otherworldly beasts desecrating the land.
Thom, the first Thom, studied the dark around; unlocking it’s secrets and securing a method of control over the plane of shadow. Turning the lost and blinded souls of the plane back to a physical existence as undead and shadow folk he secured a line, a place of safety for his people. A haven.
