We ate through the world like acid.
Seeping into the Undearth, trickling ever downward, consuming all we encountered; Never sated, never still.
Until we met resistance. Dwellers in the dark. A people who had never known war or light.
We were interlopers. Invaders from above. A light bearing race corrupting everything in our wake.
A poison seeping into cavernous cathedrals, corrupting them into corroded hollows with the light that followed us down into exile.
