As the Alpha Rune, the piece holds the true name of Ledgerdomain (Yahwahtacsip) allowing sorcerers complete control of all those within the realm and the environment of the realm itself, holding the ground where Adwaita's citadel resides intact for example, and because Ledgerdomain is known as the point where all magic flows from, it allows the user to control magic itself. It was for a long time held by Adwaita, who was already known as the most powerful sorcerer alive, who grew corrupt by its power to the point of believing all beings alive are thieves, as anything living steals mana from the Alpha Rune and in turn him. To stop these thieves he kills those who oppose him outright, enslaving the original human inhabitants of Ledgerdomain (which included Charmcaster, Spellbinder and Hex).
With its power increasing his own Adwaita easily defeated Ben, Gwen, Kevin and Charmcaster, only being defeated by a sneak attack from Ultimate Aggregor which only temporarily knocked him out. The Alpha Rune is stolen by Ultimate Aggregor and turns into its Map of Infinity form as Ultimate Aggregor leaves, going after the next map piece.
Without its power, parts of Ledgerdomain begin to crumble and without its true name being within the realm, the Door to Everywhere cannot access it although the Door can be summoned within it to escape. Without its power, Adwaita is weakened so Charmcaster decided to stay behind and free her people from his tyranny.
Charmcaster later obtained the Alpha Rune and possesses it as the ruler of Ledgerdomain.
