A genial Zaradene native in his late fifties, Biltz is the preeminent architect in Zaradene and has served the town in good times and bad. His designs are especially prevalent along the recently developed outskirts of the city, but buildings in the city’s interior that have undergone renovation or expansion also bear his mark. Biltz designed Seth Mase’s private library and oversaw its construction. In architectural projects Biltz is known for his hands-on approach, and whenever he hires crews to carry out his designs, he can be found among them at work with hammer and rivets in hand.
Biltz was among the Zaradene evacuees who founded the refuge of Adastra beneath the meadows east of the city. He is currently overseeing the interior reinvention of Clement I’s tomb to make it safer for human habitation and navigation, and was last seen designing a spiral staircase to span the gap between the balance beam room and its hard stone floor.
