Wrenford is a small city on the edge of the Verdant Expanse. It was built by a number of Orgs out of Calaria who wanted to log the copious timber in the Expanse, but the forest fought back until it was deemed too expensive to pursue. Now the city remains half-developed, never quite reaching the potential the Orgs originally saw but not dying out either.
Many of the residents of Wrenford are followers of the Green Father on top of the Host.
