Thyrrus

The Thyrrus are a squid-like alien species who see war as a performance, thus making tactical decisions based on spectacle, flash and aiming to inflict the heaviest casualties on both sides – rather than what is tactically sensible to non-Thyrrus. They made unprovoked assaults in the Segmentum Pacificus around 2.306.784.M41 against regiments of the Stemivari Imperial Guard, who referred to them by the nickname of “squiddies.”
