ADC from the Shadow Isle. Lucian's wife
The champions from the shadow isle meet every roll BUT adc. And i have come up with a doosie of a champion. Lucian's wife. not sure for her abilites, just throwing ideas out there. But her lore would consist of her telling of her time within the lantern. While she was trapped within the lantern she ends up falling love with thresh. So then he decides to let her out. But due to her time within the lantern, she can no longer return to her body. While roaming the Shadow Isle with thresh they come across Lucian. Lucain feeling sorry for his actions towards her decides to give her a choice. To stay with him and live eternally as a spirit or return to Lucian and then deal with slowly fading away. I hope that riot makes this happen, would be the most interesting love triangle and then the in-game event that could be activated or some sort of hidden debuff. Not sure but it would most definitely be something to consider. Also reasons for bringing up the fact that people can get out of thresh's lantern is that he is the chain "warden" isn't a warden a person who is like in charge of a prison or something along those lines? that's how i see the inside would be inside thresh's lantern
