Terrain - Cave
The cave systems of the mortal realms are remote and dangerous places and only the best prepared and capable venturers should enter these dark and moldy places. Those that do and safely return tell tales of gold and fortune, deep caverns and mines dug by dwarven hands. Enormous halls so big a whole village could fit inside and stone bridges covering deep pits so dark no light can reach the bottom. But there are also the tales of those unlucky men that do not return, of dragons and goblins alike. Mostly folklore of course, or so the villagers think.
