You hear that rhythmic, deafened rumble underneath your feet? The sporadic battle-like drumming, thumping at the very ground you stand on, sending chilling reverberations up to your heart and mind.

Something dark is brewing in the depths, a boiling mass of creatures starting a march-like dance, conducted by a savage, long-forgotten song, still echoing through the crevices of this old Earth.

Prepare for this joyous emergence! Embrace your new overlords!

Take care, they're rather grumpy.
