Heir(ess) is a Praesi Name, linked to both the Black Knight and possibly also the Dread Emperor/Empress.
Role[]
Heiress is a transitional Name like Squire and Apprentice. However, unlike Squire, which is strongly linked to both White Knight or Black Knight, or Apprentice, which transitions to any available magical name, Heir(ess) can transition into any available role that is available. Akua became The Diabolist simply by becoming famous for using demons and devils.
Abilities[]
The name Heiress does not strengthen the user physically but it does allow the user to manipulate other through more subtle means. Heiress' power works indirectly allowing her to manipulate individuals on a chessboard. The name also seems to enhance her magical abilities allowing the user to spar with the Apprentice.
