It is said that nobody is truly home until they have a roof over their head. Across the civilizations of Hyboria, rooves are made from a diverse number of materials - from clay-fired tiles warmed in the kilns of Agarapar to the roughly thatched rooves of the Nordheimers.
In the Exiled Lands, however, materials are limited. Something to keep the blizzards at bay and the bat demons from swooping down and snatching people while they sleep is probably good enough.
Built of planks coated in resin for insulation, reinforced by wooden slats that have been shaped to fit, this will provide a safe haven from the weather and strong front to any foes who come knocking.
