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: All right. So you manage to find bits of rock and pull yourself across the way. It's not too long a distance but enough to the point where I need you to go ahead and make a basic strength check.
Player: 14.
DM: 14. Okay. It's hard and you feel part of your muscles build up lactic acid from the exertion, from the previous round with Umbrasyl and you not being necessarily the strongest individual of the troupe, but you do manage to scurry your way up to the edge of this small opening in the mountainside. Getting inside, you get a look: this hole continues for about 15 feet into the mountain before it ends abruptly. The only other thing you notice is there are currently four long-dead skeleton corpses within this hole. Perhaps some sort of mountain-climbing expedition or travelers that found their way there, and couldn't escape. There are remnants of a small camp. Perhaps a small fire that is long iced-over through winters past. A layer of dust sits on everything and other than the occasional gust of wind that finds its way in here, largely undisturbed for a long period of time.
Player: I want to look through the remains.
DM: Okay. You rummage through the remains. You find roughly 85 gold pieces amongst their corpses and spare change in silver and copper--
Player: I don't take that.
DM: Copper. The pennies of D&D. Poor things. Copper dragons everywhere are just so disappointed. You do find an oil lantern, climbing gear for four people, some long-spoiled rations. And you find a very moldy diary.
Player: I take out the Flametongue Dagger and give myself some light.
DM: As you're scanning through most of the pages that are still intact and not completely molded over or destroyed, it appears to be a journal that contains writings of what was an expedition to reach the peak of Gatshadow, because there was some sort of movement, some sort of activity up there that nobody could really discern. The rumors speak of some sort of creature that would stalk out in the night and steal mountain goats. (belches) Pardon me. Goats! Steal mountain goats, steal or find and kill anybody who lived in-- there used to be a smaller village that lived north on the mountainscape that is now abandoned because of this creature the folklore of the time said supposedly lived at the top of the mountain. It speaks of the entrance, the place that Umbrasyl now calls the lair, and this leads you to believe that this is a fresh lair. Umbrasyl did not appear to always live within Gatshadow, but is only currently making it its lair at the moment.
Player: Is this a dead end? Does it look like it goes further in?
DM: Make a perception check.
Player: By the light of my dagger.
DM: Actually, this would be investigation.
Player: Investigation? All right. 20. No, wait-- Yeah, 20.
DM: 20. Feeling along the walls, you find elements of the rocks that are easier to break off than others, but this is predominantly the end of this cavern.
Player: It's a cave. Okay. I tell my sister it's a dead end. It's nothing. Coming.
DM: So Vax finds his way back to the group.
