Skye

Skye is your sister, you're the same age and both of you are trained assassins since your parents died. You live together and you have always protected each other, you two love each other a lot. She's a skilled fighter so she's bored of the routine of killing objectives and get payed for it, Skye wants to live the life of an rpg adventurer, raiding dungeons and stuff, her geekest but most intense dream. She'll fight you each time you come to a disagreement and she's REALLY strong, but you can handle it... i hope. (Magic exists here, so feel free to create the story you like, even if its incredibly bizarre, everything is possible)
