It's a fantasy role-playing game.

DM: You are Vex Vex'ahlia, a half-elf ranger . You are the member of the famous group of adventurers. Previously, First, you checks in with Percy to see if he can identify the pond she saw in her vision; he gives her a map and some suggestions. With a good idea now of where to go, you rides Trinket into the forest toward the Alabaster Sierras.
DM: 22. You make your way and you find the pond, and you recognize it exactly the moment you get there. This is exactly the pond in your vision.
Player: This is where it was!
DM: You glance over and start finding your way around the edge, and eventually you find the thick, heavy footfalls right beneath the water. He leapt straight out of the water so there were no tracks directly out of it, but you look just beneath the surface.
Player: I remember him jumping into the trees!
DM: Yes, you look up and you can see a few branches are broken, and you begin to trace the direction of where it went.
Player: I cast Pass Without a Trace on myself, and I'm going to stealth after him.
DM: Okay. All right, go ahead and roll a stealth check. Are you still on Trinket for this?
Player: I'm going to put him in the locket for the time being.
DM: Trinket goes into the necklace. Go ahead and roll stealth with your Pass Without a Trace bonus.
Player: Oh, right! 33.
DM: 33, okay. Very quietly, you dart up into the trees and begin leaping from broken branch to broken branch. Eventually it leads you into a small opening between a series-- the trees here are truly thick, but there's certain areas where they begin to separate a bit, and you can see heavy impacts where it leapt down and found some soft ground and begins running. And you can see the tracks, and you take a moment and study these tracks, and you can see exactly how these thick three-toed feet of the creature dig into the dirt, and you take a very, very close watch on them. I need you to go ahead and make another wisdom survival check to see where those footfalls will take you.
Player: So again, a 24. Oh wait, 22.
DM: 22, okay. So you begin darting through, and you notice there are points where it leaps into the trees and vanishes. The trail stops, but you can follow brief bits. But this creature's heavy, you can see it doesn't leap into the boughs and hang on a branch, it leaps up onto an actual tree trunk and then leaps off the trunk, and where it does, the bark splinters and breaks. Whatever this is, it's extremely dense. It's extremely heavy. And to have the power and strength to lift its form on that thickness means it has some power behind it. Continuing to keep tabs, you're darting through the dark woods. Out of the right of you, you hear a sudden noise, and you are surprised, as a series of birds come fluttering past you, apparently startled from something nearby, and you watch as a forest elk darts past and is a sign of-- you know, naturally in this environment-- of relatively recent movement. And you get the sense that you might be gaining on this creature, whatever it's charging.
Player: Oh my god, oh my god, oh my god.
DM: So as you're leaping and running and making the best possible path you can, eventually, the trail begins to grow a little cold, and you find a small glade--
Player: A small poo.
DM: Yeah, I know. About 30 feet across. The trees open and there's this space and it's pristine, untouched. The trail ends entirely.
