Nomos

A scout ship of the Nomos, an aquatic, cephalopodic species, first made contact with AltEarth in 1974. Diplomatic meetings with the Nomos--militaristic zealots who believe they are direct descendants of an omnipotent "Old One"--fell apart when AltEarth negotiators refused to accept annexation into the Nomos empire. The Nomos returned three years later with an invasion force to crush the infidels. A force of superhumans (that included many supervillians), allied with Atlanteans drove the Nomos off. Some suspect that remnants of the Nomos invasion force lie in wait in the deep sea trenches of AltEarth, awaiting another opportunity for conquest.
