**Hey there dungeon masters!**

Heres a free encounter map for you to use in your games, depicting an ancient, crumbling bridge through a vast swamp. I imagined this as a sort of ancient highway built by an empire long ago, now a forgotten ruin still used by adventurers and travelers despite its crumbling condition.

What sort of perils might await your players beneath the waters? Or, perhaps a foe bars their crossing of the bridge? Let me know how this map inspires you in the comments! There are several variants of this map available to my supporters on Patreon including night and rainy versions. Check it out here:
