Tunnel brute belongs to one of the affinity-born peoples, the native life of the Hallow that grows wherever an affinity runs strong. In its people, that affinity is Umbra. It is not raised and not called. It is a living thing, and a kingdom recruits it through its Barracks for geld, a little mana and people.
The Sealborn say its people dig toward the places where the Deep's threshold presses close to the ground, and that the dark there knits their wounds. Cut one down and it gets back up. Its blows carry a poison of the deep ground.
Fire is another matter. On the ring of affinities the dead burn, so Umbra feeds Pyre. The Sealborn hold that this is why fire eats its flesh faster than any blade.
It is kept like any hired soldier, on geld and a little mana, and its master can send it home. Like any soldier, it deserts if the pay stops.
