Out of the Darkness and Into the Light
On the Prime Material Plane, a fire elemental appears as a tall sheet of flame. The fire elemental will always appear to have two armlike appendages, one on each side of its body. These arms seem to flicker back into the creature’s flaming body, only to spring out from its sides seconds later. The only facial features of a fire elemental are two large glowing patches of brilliant blue fire, which seem to function as eyes for the elemental. Like all common elementals, fire elementals rarely speak on the Prime Material plane, though their voices can be heard in the crackle and hiss of a large fire.
Because they resent being conjured to this plane, fire elementals are fierce opponents who will attack their enemies directly and savagely, taking what joy they can in burning the weak creatures and objects of the Prime Material to ashes.
