Bastion Teeth

A hard mountain belt between the Heartland and Umbra Magni, named for the serried appearance of its quarry ridges and fortress crowns. Roads here are straight when they can be and murderous when they cannot. The Teeth preserve siege schools, engineer houses, old penal works, and veteran colonies with stronger memories than loyalties. Dwarves, orks, hobgoblins, and humans dominate the overt strongholds; kobolds, goblins, and ratfolk are more common in the underworks. In strategy, the region matters out of all proportion to its population.
