It's a fantasy role-playing game.

DM: You are Caleb Widogast, a human wizard . You are the member of the famous group of adventurers. Previously, She explains that she wants to go back someday. She doesn't know where Zuala was buried, but she has so many flowers to bring to her.
DM: Okay. First thing Frumpkin notices is the ocean here is not as deep as the Diver's Grave. It goes down maybe 300 feet. It's still deep, but it's a third of the depth you ended up having to go down.
Player: I'm going to send him in slowly larger circles over time.
DM: Frumpkin does see a shape amongst the clusters of seaweed and other bits of life that exist down there in natural ocean life. You can see chunks of ocean rock and volcanic rock, things that may have been lobbed from ancient volcanic detonations, and a tower; a sub-ocean tower that's leaning at an angle. You can see bits of broken rock based around it, and the seaweed is cluttered up around the base of it.
Player: Now are we talking architecture or natural?
DM: Architecture, constructed.
Player: I relay this.
DM: The top of it is somewhat jagged; it has sustained some erosion or damage towards its top, and it leads down inside. You can see shelves or bits where there may have been stairs or levels, but most of that has fallen inward, and from Frumpkin's exterior perspective, mostly hollow and disappearing into darkness the further in. With a 14, Frumpkin also notices a little bit of movement. Towards the very tops of the seaweed, there are humanoid bodies that are tangled in the seaweed a bit that appear to be floating there, and then one of them twitches and goes (moaning).
