It's a fantasy role-playing game.

DM: You are Grog Strongjaw, a goliath barbarian . You are the member of the famous group of adventurers. Previously, Above that, x bars against the wall where, in the center, you saw a gold inlaid seal with an empty triangular shape, like a pyramid inverted, and a series of these iron warriors that were embedded in the walls. Behind the stairway, you saw means of smelting metal and other forms of material.
DM: So that's going to end its turn. The chest slams shut now and the flames retract back inside, and you watch it exhaust smoke out each sides of its armor, and the flames that you saw burning in there are now dimmed, but beginning to flare up again. The one that's by you, Grog, is going to go ahead and move adjacently. Its head spins around for a second to look up at you and then it spins back to you, it's going to make two strikes at you with its greatsword. It has advantage on you because you used reckless.
