Perditus is constantly haunted by the dark misfortunes of his life. Deep wounded scars forever leave their imprint on him, acting as a daily reminder of his failures. Some, unknowing to the deep seeded horror behind the scars, may ignorantly ask him of how they appeared.
On a side note, Perditus was never meant to have a scar on his face but people just kept drawing him with one. I wonder if they're trying to tell me something?
