It's a fantasy role-playing game.

DM: You are Vax Vax'ildan, a half-elf rogue . You are the member of the famous group of adventurers. Previously, Tiny you, thanks to a potion that does that. Scanlan managed to go ahead and put in an Immovable Rod within its stomach, which held it up for a moment, before it decided to truly gain the advantage it needed to escape the circumstance, allowed it to tear through its body, as well as an arrow that was shot by Vex, towards her brother, in the hopes of, I don't know, being a symbol of hope?
DM: You all slowly make your way to the very mouth of the cavern. You've been at this point, as well. You wanted to go ahead and make an investigation?
Player: Scootching in, yeah.
DM: All right, go for it.
Player: 24.
DM: 24. Feeling around the exterior, there are two rocks that are nearly identical, placed at each side of the cavern entrance. Upon approaching, their texture and their weathered appearance is far younger than the rest of the stone around them, and that catches your attention.
Player: Do I need a further investigation check to discern their nature?
DM: The nature is some semblance of a magical enchantment. This is a little beyond your understanding unless you want to try and roughshod it in the way you know how.
