Rainbow Quest and steve Saga AU's

I wanted to make this Into a book but Never Got motivation to Continue it so I'm Putting it up for adoption here, Here's All of what I wrote on the Story.

AU- Fallen Angels?

Past Professor Red Pov-

"Hey Goggles! Whatcha doing?" The familiar voice of My best Friend Called out as I looked up to see him, the non steve that I had met when I was just four years old. When I had Found him He had been scared of me and everyone else but I kept him safe through everything with the Help of Colle. Unfortunately I couldn't let The New Red Leader know about him since He would kick him out because he only wanted to have red steves in his Kingdom.

"I'm making a Portal Sabre!" I told him as he smiled Widely, His Pale Silver Wings Fluttering Behind him. He had always been my best Friend, he was a lot like my Brother Colle to, Wanting to help through everything. But we knew Better then to let people know about him after what Happened with... HIM.

"ooo! That's Cool! Can I help?" He asked me as I smiled. He was the only thing that kept me in check nowadays. After the Curse I had become... Different. Insane even. Everyone was scared of me and I had Killed and experimented on more steves then I could Count. But Sabre didn't know about anything I had Done, Nor had he ever heard my titles before either, other then The Professor Part from Assistant. The Machine I had Made to Help Protect Sabre at Any cost. ANY cost.

"Sure!" I said as We both teleported to a clearing outside of The Kingdom. As I fired Up the device I looked over at Sabre and Smiled as He smiled Back. He really was like a Angel, A fallen Angel...

As the Portal opened I started Taking notes and Sabre helped by mentioning different Parts Of the Portal so I wouldn't Have to look up as Much. It was nice. He was the only person Other then The Assistant That I would let help me.

"Um..." Sabre paused when Speaking Before Talking again. "Is there supposed to be purple Chains Coming out?" He asked as I looked Out and My eyes Widened before I tried to grab Sabre to put him Behind me and out of Harms way.

...

I was to Slow as the Chains Suddenly wrapped Around Sabre as he let out a Scream. "WHAT THE-!"

"SABRE!" I yelled as he was Dragged into the Portal and I tried to grab onto him. Why did I have to be to slow? Why? WHY??

I wasn't able to Grab onto him as he fell through the Portal and it closed on it's own. I fell to my knees As I felt Tears fall from my eyes. I had lost Him. Lost the Last Person I cared about. First it was the Red King, then Spark, Then Beef, then the Elite Leader and Colle... And finally... Sabre...

...

...

...

I'm Going to find whoever it is that Took him and make they're Life a Living hell. I don't care if they're some sort of powerful being, I Will get Sabre back.

Sabre pov-

I yawned as The Leaders Talked about the Rainbow Festival that We had just hosted the day before. I hadn't gotten nearly enough sleep lately because I was helping set everything up and then Cleaning up. And then there were the Steves who threw Rocks, Trash and anything they could at my house at night to make my life horrible.

I wanted to go home. To the lab that I had helped Clean And take Care of. To the Sassy Robot and to Goggles. But I couldn't. All Because The Red steves were gone. Or that's what I was told. It didn't make sense, But I also didn't know how long I was Gone.
