Publisher's blurb: Ready to slay some ratmen in a quick one-shot? You’re probably spending hours preparing for your next session and it can be hard to find the time. We know, we’re DMs too! That's why Luke and I created this Ratmens Poison Sewer Lair 40x30 D&D battlemap. It also comes with a detailed adventure prompt that will make it easy to run a great-one shot with!
