Uh-huh. I drew this graphic a couple days ago while brainstorming for some emblems for the different races of 1,002,012 C.E. I hope you all find it as aesthetically pleasing as I do. ;)
The Skroy are horrific monsters unified under a shared mental link, accidentally created in the remote past by a human time-travel experiment gone wrong. Left unchecked for millions of years, the Skroy have evolved, and consumed everything in their path at terrifying speeds. Humanity only recently discovered them, even though the Skroy had gone so far as to infiltrate Human population centers and successfully avoided detection.
In their stealth state, they thrive beneath the ground like termites, digging vast, honeycomb-like tunnel networks deep below the surfaces of infiltrated planets. While the natives of the surface are preoccupied by the increased seismic activity and frequent sinkholes, the Skroy strike with brute force and sheer numbers before the local military has any time to respond, consuming everything in their path until it's time to move on to the next planet.
They are one of only 2 races that ever poses a threat to Humanity.
