The Brotherhood of Steel and it's Beginnings

I was planning on making a journal about Joshua's legion and their battles but I drew up more writers block than anything useful. So I want to make a Free RP with the Grand Paladins of the Brotherhood of Steel up to the moment when Joshua gets betrayed (I'm planning to do that but it may end earlier).

Here are Grand Paladins:

Name: Acutus (Aka Icharus)
Personality: Hard headed, resistant towards Joshua. Finds that his injustice for pulling him out of the Luna Wolves and into a new legion left him feeling like he failed but also having anger left.
Image: Acutus has short, brown hair, and green eyes. His face has several scars from hundreds of years of battles. His right eye his has a scar going across vertically.

Name: Caleb (Aka Plato)
Personality: Intelligent and strategic, Caleb was once part of the Emperor's Children but was removed and gifted to Joshua from Fulgrim. He always has a calm attitude when facing danger or anything for that matter. He is an over perfectionist when it comes to anything.
Image: Caleb has no scars on his face. He has a spuare jaw, white hair that he puts up in a pony tail, and eyes are blue

Name: Augustus (Aka Chratos)
Personality: Out of all the Grand Palandins, Chratos is the most violent. He would bring his chapter into a battle and turn it into a slaughter. He was formally in the World Eater's legion and was forced out as a gift from Angron. He despises all his fellow Paladins.
Image: Augustus's face is uglied with scars and on the end of his cheeks was a torture cut which makes his lips look like a grin. (Sound familiar *stares at Silent*) His eyes are hazel and he has no hair.

Name: Batu (Aka Socrates)
Personality: Considered the wisest of the Astartes in the Brotherhood of Steel. He cares for all his brothers, even Augustus. He is inventive when it comes to new weaponry and armor. Gifted to Joshua by Farrus Mannus (I think that's his name)
Image: Batu has black short hair that he slicks back. His face only has one scar that stitches across the face diagonally right.

I can't think of any other characters. Whoever wants these their up for grab. I'll come back to this thread when I think of any other good ideas.
