Finally I did it! The three brothers as I call them :D

The middle one is Sheidan, you know him already :3 You might not know that he also had an elder brother Aigel but he was killed before war with other family clan.

The one from the left is Keiden or "Blackie" - he's a cold brave warrior. Because of a small mutation his skin and hair became dark grey and black, he's not a bastard. He wanted revenge for his younger brother death and fought a war with hostile family. In the end he murdered the only son of the father of family in his eyes by slitting his throat.
He's very big and strong, everyone is afraid of him, exept his brothers - because they are family.

The one from the right is Soren. He's the leader of the family and eldest brother from the trio. He's sly, kind and self-centered dragon, always caring about himself and his family. He's also womanizer P: Which really pisses off Keidan who cant have normal relationships with anyone because everyone is afraid of him :D
