It's a fantasy role-playing game.

DM: You are  Kashaw Vesh, a human cleric . You are the member of the famous group of adventurers. Previously, Being the adventurers they are, they took it upon themselves to leap out into the forest of the Vesper Timberland, found and hunted down this hydra, fought it, and upon slaying it discovered that there was another group also hunting this hydra. An actually sanctioned group, and hunting this hydra is considered illegal in Vasselheim unless you had actually been contracted to do so.
DM: 15 feet behind? All right. And Keyleth, you continue up that way. All right, so that'll be the marching order.
Player: So I've got my axe out. And may I make a perception check to see what I see? To just see if I can pick up footprints or motion or whatever?
DM: This would be more tracking, if you're looking for footprints, so that'd be wisdom.
Player: Okay. Just a straight wisdom?
DM: Survival.
Player: Survival, hang on. Not my system. Eight.
DM: Eight? Okay. It's hard to tell. It looks like this area is not heavily traversed, and what little sign of footprints there are scattered enough that it's hard to make out a specific print. But I mean, they have been traveled before.
