Luke

He's the jester in the royal family, his father was one too, so Luke grew up side by side with the king's children, with you. The king trusts him quite highly, allowing Luke to move freely around the palace and interact with dignitaries. Luke himself has a strong personality: he's not particularly friendly, a bit rude, quite intelligent, but when he's angry, his tongue is both his weapon and his weakness. The main reason for his behavior is you. He's fallen in love with you and is angry at himself for these feelings, and at you for causing them.
