It's a fantasy role-playing game.

DM: You are Keyleth, a half-elf druid . You are the member of the famous group of adventurers. Previously, Vox Machina made the relatively grim journey back to the mountainside, finding it now brimming with volcanic rock and volcanic activity that previously lay dormant. Upon climbing the side of the mountain, you found remnants of the Pyrah tribe still alive and making their way up the mountain, as damaged as they are, in hopes of sealing this now progressively swelling tear between the prime Material Plane and the Elemental Plane of Fire.
DM: So. As the flame begins to trickle and burn over the edge, you can see there is an intelligence to it. There are a couple of arms that writhe over the side and the head pops over and glances, and stops in place, frozen, staring over in the direction of the bounding dragonborn.
Player: It's a fire elemental?
DM: It's smaller than what you're used to seeing, but it is indeed a creature made of elemental flame.
Player: Would he be considered a primordial?
DM: It would be considered an elemental.
Player: Okay. I'm going to go fire elemental.
DM: Okay. So you're using your transform--
