Diego: Diego used to be part of a pretty rich family which had the last name 'Windglow'. Now the Windglow family didn't really have a good reputation with another family which had the last name 'Pinewolf', the Pinewolf family were always rivals with the Windglow family. Now one day Diego was walking back to his house when he saw his house was on fire! the Pinewolf family guards were attacking the Windglow family, Diego, who wanted to see if his family were still alive, went inside through a broken window and went to the room where his parents were, his father, Rico Windglow, was on the floor, bleeding to death, Diego walked over and Rico said to him "Diego... I don't have much time left, go! go to the Dawnstream Mountains!" without hesitation, Diego ran to the mountains. After getting to the mountains he met his friend, Onyx (who is a hyena), Onyx wanted to help Diego find out who killed his family.

Onyx: Onyx came from a poor family in the Dawnstream Mountains that didn't have much money, Onyx's family got Onyx to join a band of thieves to make money. Life with those thieves was going alright, all the jobs were getting done properly until something happened. A traitor alerted the guards of the thieves and got the guards to attack, every member either died or fled. This caused Onyx to go back to the Dawnstream Mountains where she'd meet Diego

Xavier: Xavier used to lead the band of thieves before having to flee, after he ran he met the head of the Pinewolf family who was leading the guards, after making an agreement Xavier became a guard for a couple of years until he worked his way up to become leader. It was also said Xavier's sword was magical but no one really knows for sure

Scott: Scott was living in an abandoned house because he got banished from his village. Xavier found him when he was taking a walk and offered him a position as a guard, Scott agreed to this and joined the Pinewolf guards where he has been working for a while now. Scott doesn't really know what he's doing there and only takes orders from Xavier
