Joran Wraith is another Mandalorian warrior who answered who answered Jango Fett's call to join the Cuy'val Dar. Joran trained several Commando squads as well as later generations of ARC Troopers, whose ranks had been filled by standard clones that showed above average skills. He became a father figure to the four members of Nexu Squadron, a team of clone commandos and would often treat them as though they had been biological sons of his. Joran Wraith butted helmets with Sergeant Jast Tal'oor a few times over their ways of training the clones, but became good friends by the end of the Clone Wars.

Also, in regards to his hair, beard and tattoo, I was trying to go for a viking type look.
