It's a fantasy role-playing game.

DM: You are Keyleth, a half-elf druid . You are the member of the famous group of adventurers. Previously, They arrive without too much trouble at a point directly above where Vex senses the sword. you glides through the earth as an elemental, but is unable to find the sword, so Vex decides to look for it by dousing herself in Oil of Etherealness.
DM: Okay. You coast along the outside and you can sense that you're traveling on the outskirts of this descending tunnel where the acidic liquid is encased, and eventually it rounds out.
Player: I do another sword check.
DM: Make an investigation check.
Player: Am I at disadvantage again?
DM: No, because you know what you're looking for.
Player: That's good! Don't fuck me, Gil! 16.
DM: Okay. You reach out and you grab forth, and you feel a few things that you grab and as you sense them, you poke your head through, which in the process of doing, you do suffer six points of acid damage, and your hands find bones. And glancing through a little bit into the space, you can see the entire bottom of this basin is bones. Probably a good four to five feet of stacked bones. This has been used as a means of disposing of unwanted things.
