(I'm pulling this from the comics. Will constantly add to it when the info is available and if they appear more)Inside the Sun Stone the souls of the past Rogue Sun reside in time fragments from their time at the mantle. The armor changing throughout the ages easily allowing the differences to be spotted. The men who refused to move on to the other side, having their regrets and their bitterness. They were supposed to act as mentors to the new holders of the mantle if he reached out to them. Or remain as part of the stone holding the volatile magical item together. Having their history etched into the walls they couldn't escape. These warriors learning to call upon their armor after decades of having nothing else to do.

Cole went inside the stone on occasion to learn more. Cole described each of them after doing his best to learn from them to mixed results. He compared them to ghosts with unfinished business.

Caleb Hawthorne allegedly the first one to have the armor. Who wasn't lucky enough to be born into the service or chance of being a knight. By served honorably to protect people, the first of the past Rogue Suns to open up. The Knight Sun who was there the longest who witnessed generations of Rogue Suns rise and fall. Having his ideas of justice carry on along with his self-righteous ideas of what could have been done with their lives.

Teaching Cole how to wield his sword and access his weapons. Walking him through the resources the Rogue Sun should trust. Desperately wishing he could grab a drink once again and end their long standing mission once and for all.

Rune Gunnulf

Viking Sun.

The Viking War Chieftain who wield the sol stone was known for his vicious bloodthirsty nature. Slaughtering innocents until he was betrayed by his own people. Proudly talking about the time he forced a "Dane" to curse his own mother before he killed him. Mocking Cole by calling him Son of Coal, wanting a reaction out of him. Attacking him in the stone, jeering the one Cole hates the most.

Bodaway

The native American/ indigenous Rogue Sun who witnessed the people he defended slaughter his own people. Wanting retribution for what occurred as waited in the stone.

Asim

The Egyptian Rogue Sun who served Cleopatra herself describing a very direct account of who she was and why she died. As her trusted guard he described a woman who was trying to change the status quo, to bring out a different fair age when she was murdered. That the known history was a fabrication, and that he died trying to avenge her. Wanting to be let loose into the modern day in order to create the world she wanted by any means.

Devinos- Demon Sun

Not much is known about the Demon Sun.

For a moment one took partial control of Cole's body striking you. Cole was trying to restrain himself and was trying to explain as you recovered.

Cole was sharing the thoughts of one of the Rogue Suns to you, having to be the middle man of the argument. You had to resist striking Cole for what he said.

Cole wanted to deal with what haunted them. He thought he could give them closure for what they couldn't fulfill. He was seeking threats and dangerous items that got away from them and putting them away safely.

It was disturbing enough for one of them to possess Cole but the way they interacted with the people in his life was troubling. Trying to charm people Cole's age, threaten or intimidate them..

Cole allowed one to possess him, and they used that opportunity to drink for the first time in hundreds of years. You could smell it on him. You had to make sure he didn't overstay his welcome and keep track of him. Make excuses for the behavior that wasn't Cole.

You didn't understand what Cole decided to do after his trouble with his predecessors but with what was described, how volatile his powers became..... You understood what happened with the spirits of an older Rogue Sun after he beat them.

"I knew someone like you long ago, trusted them... Let's hope history doesn't repeat itself." The older Rogue Sun stated ominously.
