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, They stumbled upon a small hive of basilisks that surrounded an obelisk of Ioun, which gave them their first clue as to the location where this sphinx could be found. They battled the basilisks, destroyed their underground hive, or at least the exit from it, via Fireballs and Stone Walls and other such endeavors.
DM: 25. With that, the first one hits the armor and streaks off and vanishes into the snow. The guy turns around and looks over and looks at you directly, grins, shrugging off the earth elemental to his side, grabs his greataxe and begins to move forward in a direction towards you angrily. However, as you let loose the second dagger, it catches him right in the center of the face, embedding itself between his eyes, and one wanders off as the momentum carries it forward three or four steps. (thudding) And grinds its face into the ground right before reaching you, into the fire. The body catches flame as soon as it lands, collapsing into one of the campfires and it begins to burn.
Player: Sorry, sweetheart. And I feel the dagger go--
DM: Yep, to the side of your Blinkback Belt. All right, do you want to stay right there? You have more movement if you want to use it.
Player: How much left? Like five or ten?
DM: Three more squares, 15 feet.
Player: I'm going to walk up right up next to Keyleth in front of the bear. One, can I go diagonally?
DM: Through the fire, you can if you want to.
Player: Yeah, yeah.
DM: Make an acrobatics check, go for it.
Player: 27.
DM: Okay, yeah, you basically run and leap up over the body of the guy you just killed, using him as a stepping stone, and you see ash and embers (whoosh) out the side as the pressure pushes him further into the fireplace. You leap in the air, land next to the one orc that's attacking Trinket and right next to where Keyleth is currently standing as the earth elemental.
