I look at my Glyos storyline like a television show - in terms of seasons and such.
One of the seasons ends when the denizens of the Glyos system meet Monstrous.
An earlier season ends with what is thought to be the ultimate showdown between Exellis and Pheyden. Pheyden finally tracks down Exellis and demands that Exellis pay for the crimes he has committed against the Glyos system. He activates the Kromnet suit, thinking that there is no way that Exellis will be able to defend against it.
But Exellis has a Kromnet Suit too.
Stars die as the power of two Kromnet suits battle against each other. Pheyden and Exellis fly through space, their bodies slamming through entire planets and reducing them to rubble.
It takes a unique thought on Pheyden's part to finally overcome the power of the suits...but that story will have to wait for another day.
