Gew'Len - Ghost of the Void
"My body was remade when I was thrown into the void, it actually killed me. The void is a dark place, you must never go there. Everything that comes from it is riddled with obsession. It tried to change me, and I resisted. It succeeded anyways. I cannot explain how, but I am living beyond my body. I have become death, I will seek revenge. I will seek revenge. Who did this? Who threw me? I am soul, I am eternal. Who made me? I can't see anymore, there is blood on my breath. Breath? Breathe? I can't breathe...** I am suffocating**"
(Appearance) small void-like girl with a ghostly aura and transparency. Long hair down to the ground, pale expression, no eyes. A small light follows her and is unexplained, which Gew'Len has simply named "wisp" (Role) Mage, Manipulator identity The true ghost of the battlefield, untouchable, haunting, a nightmare. (Abilities) <Pas.> Shiver - Gew'Len can move through units, when she comes into contact with an enemy she applies a 35% slow for 1.5 seconds. 3.5 second cooldown.
<Q> Hauntmare - Passive - Gew'Len only takes 50% duration from fears Active - Dashes a short distance and fears an enemy for 1 second. If Gew'Len autos the feared enemy she inflicts 75/100/130/150/180 +30% ap as magic damage. If she doesn't auto attack the enemy she gains a spell shield making her a true ghost of the battlefield. 10 second cooldown all ranks.
<W> GhostWalk - Merges with a wall for 1.5 seconds becoming untargetable by direct damage and then clicks to appear on whichever side of the environment she chooses. 18/17/16.5/16/15 second cooldown.
> I just want to clarify, this is a dodge to any direct damage. Gwe clicks on any environment she can touch and merges with the side of a wall. After 1.5 seconds she basically can appear at any other side of the environment she is inside.
<E> Soul Bond - Has different effects based on enemy or ally cast. Direct damage tether cast. 12 second cooldown all ranks. Cast on enemy: Reaps the enemies life force dealing 50/65/85/90/100 +25% ap per second for 4 seconds, heals Gew'Len for 75% of the damage dealt. Cast on Ally: Rips 10% of Gwe'Lens health and heals the ally for double + 5/7/9/11/13% ap over 4 seconds.
<R> Will o' the Wisp - passive - When an ally champion or enemy champion dies, consume their soul (stand on their body for 4 seconds) and gain 1 stack of Will of the Wisp
active - consumes all Will o' the Wisp charges (5 charges max) and throws out wisp in a line. The first enemy it hits is inflicted with 75//125/150 x (will of the wisp charges) in true damage. If will of the wisp kills the enemy, only one stack is consumed and after 5 seconds will of the wisp can be cast again. 220/200/180 second cooldown.
> Something to note, the spell wont do 0 damage if you have 0 stacks, you simply cannot cast it until you obtain stacks. After 5 seconds will of the wisp can be cast again, but this time you will have 1 less stack, if you manage to obtain another kill with this reset the same effect applies. Lose another stack and cast again in 5 seconds. Note: You will have a short period of time to cast this spell again, like 5 seconds.
Gwe' should have a lot of interactions with void based champions, especially Kassadin and Malzahar.
She also has some unique interactions with undead champions,
and 
this is her DANCE!!!
