Darkmount (Cybertron)
| The name or term "Darkmount" refers to more than one character or idea. For a list of other meanings, see Darkmount (disambiguation). |

Darkmount is an ancient fortress on Cybertron, the capitol of Decepticon-controlled Polyhex. It was built long ago around the caldera of a great magma plume welling up from the center of Cybertron. For a period of time during the Great War it was the seat of power for Lord Straxus, who fed dissenters to the smelting pool, a cauldron of magma which sat menacingly in Darkmount's shadow.[1] The smelting pool empties through ducts into a canyon which Darkmount overlooks.[2]

Darkmount was built in ancient times around the natural smelter known as the Upper Pool, to defend it from primitive creatures spun-off from the Transformers' own creations. Below it lay the Lower Pool.
In the last days before the great war, Darkmount was basically a large inhabited ruin. The settlement of Polyhex spread out from its flank, separating the Upper Pool of magma from a series of high class upper-caste homes on the opposite cliff face. Below, a community of artisans made their homes around the edges of the Lower Pool. Exodus
