Chess-set

Origin
The chess-set is part of an ancient system used by powerful demons and angels on Earth in order to supplement their ranks with beings not originally part of their race, as well as to increase the combat and non-combat abilities of their preferred subordinates. It did not exist on Terrok, and has been introduced due to research performed by Lilith, Crista Sakurazaki and Vanessa Quinn on Riko Silvian's chess-set, which had been reset upon her arrival on the planet. Sets have then been given to specific high-ranked demons, as judged by the three girls.

Usage
The chess-piece is used by it being inserted into the (willing) targets chest.

Upon insertion, the receiver transforms on a spiritual and genetic level, obtaining the same traits of the race the King, or owner, of the chess-set belongs to. Abilities of the king's sub-race or secondary race are transferred as well, but to a lesser degree. The original abilities of the receiver are not affected. However, the overall effectiveness of the users abilities depend mainly on their own level of skill, as well as their practice with the newly acquired skills.

Each piece of the set additionally grant unique boosts, depending on the piece in use:
 * King: The owner of the set. Has the ability to Command the other pieces, forcing them to obey the given command. Additionally, the King has a limited ability to teleport the other pieces to him if necessary. The King also has the ability to designate any other of their pieces as their heir, whose piece will mutate into the new King piece in case of the King's permanent death or disappearance.
 * Queen: Gains the buffs of the bishop, rook and knight chess-pieces, greatly boosting their physical and magical prowess.
 * Bishop: Grants the wielder a boost in magical abilities, no matter their source.
 * Knight: Greatly boosts the wielders speed and agility.
 * Rook: Provides a large increase in the wielders physical strength and durability.

The pieces belonging to the same set also gain the ability to telepathically communicate with each other across long distances.
 * Pawn: Grants the Promotion ability, which enables the pawn to promote themselves to any of the other pieces, except for the king piece, while being in an area designated as enemy territory by the king.

While not required, the kinder kings prefer to grant the people they want to turn into chess-pieces a quick and painless death, in order to spare them the pain of the transformation. If a piece is used on a recently deceased person, that person will be revived as a new chess-piece.

Each set seems to have a different color depending on the species of the King piece. It is black for demons and white for angels. The color of other species is currently still unknown.
