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, From the mummified body, they loot an adamantine hammer and a gray leather belt studded with opals. Grog takes the hammer, and Percy puts on the belt.
DM: I know. As you crest the top of this upper area of the road, you glance down and can see a portion of it is underwater, there's a small pool where droplets drop and at the edge of it you can barely see the shape of a creature, hunched at the edge of the waterside.
Player: How close am I to that?
DM: It's about 50 to 55 feet from you.
Player: Divine Sense.
DM: Okay. Divine Sense to see if--
Player: It's undead.
DM: It is not undead; you do not get an undead sense.
Player: Okay. Or a fiend or a celestial?
DM: It's too far away to get a close view at this point because it's at the edge of your darkvision. You can just make out its shape; it's humanoid, it has two arms, two legs, and it looks roughly the size of you or Vex. But you now see it's sitting at a fallen and partially ruined dwarven statue, some sort of structure that was on a pedestal that had fallen at the edge-- and it's sitting over top of it. It's got gray, splotchy skin, tough exterior, armored spines or plates along its back that stick up as it hunches forward like some sort of porcupine.
