Void champion with a twist

Here is my idea. A girl who grew up in a nomadic group of peoples. Her group is attacked she is taken and sold to scientists of Zaun. These particular scientists have captured a strange creature they believe to be of the void. A mass of purple (because everything from the void is purple lol) ooze basically. They have purchased this girl for some sort of testing. Something goes wrong and she and the void creature are fused together. Though now of one body she now has two minds in her head. Her original mind manages to keep control most of the time but not all of the time. She now posseses the power to create things from the void ooze to her advantage. I thought it would be interesting for her to be a hyper mobile mage. Using her ooze to form tentacles that can latch onto walls (sort of like nautilus' anchor) and other objects. Maybe even champs. Her ult would consist of the void concience taking over. Thats all i have so far. I have a colored sketch that i will attach soon but it is rough. I will do a high quality black and white drawing but I have no knowledge of digital art so thats as far as I will get. Her name is Xen'ra, hand of the void.
