Kerberrus was born in a small humble house in Bree, growing up dreaming of being a skilled Captain. One day, his parent traveled to Buckland as they were ambushed by bandits.
As his father was a stub-born person, the robbery turned into a murder as the bandits killed both his parents. Kerberrus promised that day to help anyone who is under threat.

At recent years, Kerberrus began to assist the people of Bree-land as he met a mysterious woman inside the Bee and Barb who lead him to a whole lot of an adventure which led to the meeting of Ragnoaso and the Secret Order. The Thane of Riddermark saw the potential and invited all of the able-bodied soldiers into his court.

Currently, Kerberrus is serving Thane Theodvan of Riddermark, Rohan as his personal advisor and guard, looking for the well being of the Thane, Thane's family and the people of Bree.
