So what if varus' sister ....
What if the Darkin ended up inhabiting kassadins daughter and because of her void thing ended up being corrupted, and to seek power she wishes to fill he siblings and runeterra with that of the void. But after years of resisting the void kassadins daughter is partially able to control her self with the energy of the Darkin having partially restored her mind. So a stance swapping champ that could play as a support or mid laner with Darkin void icathyn and (possibly Shurima) influences?
