Summary
Ignis Prime, was dead.
Cybertron lived, but it had come at a cost, and that cost this time, had been Ignis.This however, is far from the end of the story. In fact, it is just the beginning.
Especially when Ignis Prime is found. Alive. Barely, but alive.
Only time will tell what fate has in store for him, as this is just the beginning of the rest of his life.

Conjunxed Since the Days of the Force by jane2001673

Summary
From their early days as officers in the Enforcer era to the heavy burden of the Prime lineage, Prowl and Optimus have always been more than just comrades—they are Conjunx Endura. But the shadows of the Great War run deep. Despite the scars left by old alliances and the ghosts of their past, they strive to rebuild what was lost and raise a family in a post-war world. A story of healing, duty, and a love that refused to break under the weight of Cybertron's history.
Warning: Most of this work consists of smut, fluff, and family-oriented humor; however, please be advised that certain chapters contain non-con. I will place specific content warnings at the beginning of those chapters. Aside from those chapters, the story primarily focuses on the ProwlOp family dynamic.

Jazz and Prowl are Paranormal Investigators.
They had been looking for evidence of the paranormal for years. The two of them investigated everything from aliens to ghosts. To Jazz's disappointment, they had never captured any real evidence. When their friend Blaster sends them reports of large figures being seen in the woods and cars being seen without drivers, they think it's another hoax. After all, everything else they've investigated had ended up being fake in one way or another.
Unfortunately, what they find is very real, and it makes them question everything they thought they knew about themselves. As their strange encounters keep happening, they can't help but notice impossible changes in themselves.

Summary
Rodimus, being Rodimus, thinks that nothing could possibly go wrong with forgetting to take his suppressants. He finds out that yes in fact, it can.
Rodimus’ processor felt like it was melting and every second that passed, his HUD pinged another cooling request. And every time he dismissed it, his vision glitching around the edges as he did.
Maybe he’d caught something planetside? Maybe some stray virus they hadn’t been briefed about? It wouldn’t be the first time he’d attracted trouble with zero effort.
He glanced around the room, scanning his crew. No one else seemed affected, or looked like they were melting alive. When his gaze landed on Ultra Magnus, he found those piercing blue optics already on him.
Uh oh.
Or: Rodimus has his first heat and it takes him a stupid long time, and several overloads later, to realize it.
