Dents is an anomaly among the other members of the horde. He is actually very pretty, along with having a soothing touch that makes him ideal as a battle healer. Dents was raised as a warrior, and he was taught to fight for his kills. Murdering boars were a common occurrence around his household, but he did not like doing such things. He preferred to help out when his brothers and sisters were unable to defeat their prey and got cuts or bruises. Eventually he learned that he had magical powers which could miraculously close the cuts of those around him.
Dents soon was put to work using these powers and soon became the village healer. Day in and day out he would heal the sick and wounded until they stopped caring about getting hurt and taking his abilities for granted. On one such day a little boy who he should have been able to save died because he did not have any more power left. The soul of that boy haunts him to this day.
Eventually he was conscripted into the military as a healer far from the battles taking place. He was very good at his job and eventually he worked with Thrall on some of his missions versus the Alliance.
He has a general hatred towards the "pretty races" as he has to fight to maintain his appearance and really stands out in a crowd. He feels like they are accepted more the more they are beautiful and hates that he is looked down upon for not having scars of battle and an unkempt appearance.
Dents is more of a laid back narcissist than anything else. His priority is making sure he looks good, but also making sure others look their best. He figures if everyone looks pretty, he wont stand out as much, so long as he is the prettiest. He is outgoing and willing to work with almost anyone, so long as they don't intentionally/indirectly try and cause him harm.
