Aksana is Chancellor of the Trantherian Empire and in the Emperor's absence the current ruler as well. She appears to be a young Shin woman. Both the human Vexerad and Commandos answer directly to her, not the Emperor. She is an extraordinarily talented assassin, and her human pets are trained to emulate her fighting style and abilities.
Since the Emperor’s disappearance and her draws from the Shimmering Deck, she has become more haughty and demanding. She is no longer even remotely deferential to anyone else in the Trantherian government, and she will only negotiate with heads of state, having no time for dealing with their representatives. If she deems someone a threat, they will be eliminated unless the Emperor himself intervenes. This is what saved Laurazhi du Gray and her sycophants.
