This is Fort Spearmount, a place where the strays rule supreme and pray upon the lost. After finding a strange cave, you’ve been captured and cast into this place to die, however that may happen.
Here, resources are scarce, so you can’t prepare for anything. You’re only options are to stay hidden, stay out of reach, or fight with your own hands. Put simply, you’re going to need a steady mind and brave soul if you ever hope to get out of this place alive.
