Kallahan-138, a Spartan-II OC of mine, was born and trained on Reach, leading him to become extremely traumatized after it was glassed by the Covenant. He barely survived the battle himself, escaping to Earth, only for it to be attacked itself only a short time later. Most of his friends literally died in his arms, and the scars on his armor and body are nothing compared to the wounds within, carefully concealed behind his casual attitude.
