Description

Made this one as a two-part encounter: a quiet frozen lake dotted with glowing crystals, and then the same map after something ancient breaks through the ice.

The idea is you run the "Before" version while your party explores and maybe harvests a crystal shard or two — then swap to "After" the moment they push their luck too far and the Frozen Maw's tentacles come up through the fissure.

Comes in Day and Night lighting too, so 4 scenes total, plus grid/gridless and a few stylized variants (anime, comic, woodcut) if you want something different from the standard look.

Foundry/Fantasy Grounds/Roll20 exports with dynamic lighting baked in, plus a DM booklet with side quests and a statblock skeleton for the Maw if you want to build the fight yourself.
