"Voracious, chitinous creatures that spawn from hives deep below the Earth’s surface, Scylla Formicida – or 'hellbugs' as they’ve been labeled by human and Votan alike – were created from the terraforming processes that ravaged Earth. They are neither truly Votan nor terrestrial in origin, bearing characteristics from a variety of species across multiple planets."
