Norunners

There was a Forerunner named Kellek who was an enemy of Roah.  He got exiled deep in the Earth's past and spent those days trying to construct gates to get back and exact revenge against his rivals who were back in the present he was from.  Some of the Niode Gates he made using those primitive materials and what he could salvage from his wreck were not exactly right so in his trial and error a few of Kellek's gates took him across space but on alternate timelines instead of a linear manner.

One such universe was what is referred to by some people as the Negaverse.  It is a foul and twisted dark dimension that is a mirror of our universe.  The Forerunners there are a rather evil and warped version of the Forerunners from our universe and well, some way or other they ended up worshiping Kellek as a God.  Horrific mutations and ceremonies of transmogrification became fixtures of religion and of cultures in this poor unfortunate dimension. It evolved separately in parallel from our own home universe but the two exhibit certain striking similarities between them.  For example, these NoRunners possessed Kaiju mecha too but instead of beast mecha they are classified as Eldritch mecha... Trundling legged tanks with missile platforms, swift tentacled bizarre ice mecha and freakish armored crustaceanoid laser based mecha that have claws.
