Sly one Devs....but I caught it!

Considering the pop culture references sprinkled throughout the game it seems entirely plausible.

Of course in the case of the Devouring Earth it also makes sense in that Tellus is an obscure alternate term for the Earth since Tellus was the Roman goddess of the Earth. The first time i remember seeing the word Tellurian used was either in EE 'Doc' Smith's Grey Lensman series or Skylark of Space series. So there's no guarantee that the writer wasn't inspired by mythology or other writers instead of Star Trek. Especially since the CoH version uses the correct spelling of "Tellurian".
