1: The mysterious guy, who give Ratchet Phenmor and rescue him from Jack and Drifter, was Kaden. Yes, his body was hijacked by evil version of Albrecht Entrati and therefore killed, but thanks to Conceptual Embodiment, Kaden was "recreated" by The Void. He learn what happened and wanted to get revenge for him and his son.
2: Ratchet was a creature created by The Man in The Wall, who combined three DNA. Kaden's son, a Warframe and Tenno from different universe, making his own Void Demon. So Basically Ratchet wasn't Kaden son, but only had a part of his DNA.
3:Kaden's son, named Ragna Rook, was imprisioned in Duviri Island, a realm within the Void. Kaden learn about it and wanted to rescue his son by using Ratchet, whom he firstly saw as a tool, but then start treating like another son.
4: Ratchet and Rivet were suppose to meet during a Dreadzone. Didn't had idea how Ratchet would get there, but Rivet would be kidnapped, because I wanted to make Vox work for Lombax Empire.
5: Jack was suppose to be a leader of his own faction called Cult of The Whisper and be a very serious threat.
6: The Man in The Wall was suppose to be a antagonist too, but also an Ally from time to time for Ratchet. (He didn't want Jack to conquer all multiverse and took out his fun, which is messing with mortals).
7:Later in story Rivet was suppose to become infected by a same virus, that is Ratchet made of. She would then become an Gunslinger.
8: Ratchet was suppose to be an evolving hunter, who kill creatue like him and eat their hearts to get their powers, like dragon's breath or Werewolf's claws.
9:There was suppose to be a few Albrecht Entrati. One that is fighting against the Man in The Wal, another who help Lombax Empire, and a last one who is helping Cult of The Whisper.
That most important stuff. Some of it may appear in the new version, but it's very slightly %.
