Key of the Slave
Your character is owned by another character. Every time the character sees to his master's needs (either following an order or by his own initiative), he gains 1 XP. If this causes him discomfort or inconvenience, he gains 2 XP. He gains 5 XP if this action causes him harm, pain or despair. Buy-Off: Openly defy your master's order, or gain your freedom.
