Summary
Your life is a filthy nest of your own ineptitude, a monument to your wretched uselessness. You are, by and large, waiting to die. But it would be a kind mercy if something could fit into this hole in your chest before your life gives out. You'd like to be at peace, at least.

Summary
Starscream is the Air Commander of the Decepticon armada, Megatron’s Conjux, and the exhausted carrier of highly chaotic sparklings. His life is a delicately balanced schedule of managing a Warlord's tantrums, dealing with his Autobot ex-lover Skyfire, and keeping his fiercely addictive, secret sessions with Soundwave under the radar.
But when the stoic Soundwave decides he’s no longer willing to just share the shadows, and Megatron’s unresolved obsession with Optimus Prime reaches a boiling point, Starscream’s perfectly compartmentalized life goes entirely off the rails. Between an expanding polycule, unexpected pregnancies, and a Decepticon High Command that functions more like a feral family, Starscream is about to learn that you don't have to choose when you can simply conquer them all.

Old hatchets had been buried, old grudges had been temporarily put aside and new relationships and alliances have finally formed.
Yet, the fate of Cybertron still lingers over so many sparks, unknown and dreaded, but luck will eventually struck when something out of space come to join the party, bringing way more than what was bargained for!
