Nail of the Ape

The distinction between ""sprite"" and ""abomination"" is merely a matter of name. A sprite is tamed and obedient, while an abomination is an uncontrolled misfortune. This nail embedded in the body of the Malefic Ape serves as an eternal guarantee of its status as a sprite.

""As a disciple, it is your duty to obey. If the Master Primus drives this Possession Nail into your body, then you will have no choice but to obey, won't you?""
