Adversary Heir - New pack rank idea

Sirius will be making a pack sometime in the future that will be an extension of the Ashen Empire. One of the ranks in his pack will be 'Adversary Heir' There will be two slots in this rank (one is already filled) The idea behind it is that in the event of the Alpha's demise, the Adversary Heirs (Which will be trained to be rivals) will have a dominance-style challenge to determine who will become the next Alpha, and who will become slave. its a very high risk/high reward rank that I think could be an interesting plot twist. If anyone is interested, or have questions, feel free to post them!
