This battle map is essentially a test drive of the new Dungeondraft software, which I'll be using to make local maps. The software isn't particularly stable as of now, given its still in early access, but it is surprisingly powerful and easy to use. I look forward to working more with it!
As for the battle map itself, this is meant to be a nobleman's house - in particular, a nobleman war veteran and combat tutor, thus the training dummies, armor stands, weapon racks, etc.
