An ancient battle was fought at this site. The name Fort Grimstone is mostly lost to history.
Local history says that a great host had built a large site there and in a great battle a volcano was summoned into the middle of the camp.
What remains is a mountain with tunnels created either by those trapped escaping or by those from the outside digging in to discover what laid below.
The power to summon a volcano is currently unknown in the world. No recorded histories are known to mention such a powerful capability and no record of the events surrounding Fort Greystone are captured beyond the myths of the local Bane followers.
