Wayyyyyy back, I wrote about the black hole, and the reversed universe that had an evil Pheyden running it with Exellis as the hero.
In our Glyos universe, Callgrim was a hero who met his untimely demise at the hands of the evil Red Scar Pheyden.
Finally, he can be shown. He carries a Sarvos helmet to disguise himself in their ranks, and a double-blaster that can quickly take down gendrones in battle.
Callgrim would later be brought back from the grave by mysterious forces, twisted to the side of evil during his resurrection...
