I'm writing a Universe Trilogy right now, and have finished the first part.
"Conflagration" takes place a year after Beast Machines; Predacons in exile on Charr, outraged over the reformation of Cybertron, launch an invasion on the weakened Transformer homeworld. The war bogs down in the capital city, which is where the story takes place . . .
I realize that this goes to an outside link; I'll post it to D-City once the board has some more kinks worked out.
