Evelynn doesn't have any modifying skins, a weird kit, and an outdated model/icon. Her lore is too vague and she hasn't been seen anywhere for quite a while. She's like the shy kid in the corner who is ignored. 
Just pointing it out there.
She's stealthed. She'll probably turn up eventually.
I like her lack of lore, I think it fits her. As for where she is, when she's not hiding with her passive, riot is pretending not to notice her because she probably needs a total rework but isn't as bad as the other champs on the list.
