Ultimate Skin: Senna the Purifier (complete visual/audio/theme overhaul for Lucian)

Hey everyone! I don't usually post here, but I thought this was worth it.

I've thought about this idea quite a bit, because I've always thought the interaction between Lucian and Thresh was really cool, and with Kalista thrown into the mix, all of a sudden there was lore basis for this skin. Unfortunately for Senna, there is no way she would really be able to become a champion in her own right, simply because of heavy lore/thematic constraints. But as a skin for Lucian? Oh boy.

So there are two different possibilities for this skin in my mind. First, it could be a sort of "what if" scenario, where it would be Senna if Lucian had died in her place. And while I think that idea is cool, it doesn't really seem quite like ultimate skin material. Instead, I propose option two:

Senna is tricked/betrayed by Thresh, and he steals her soul. Lucian cuts down thousands of undead until he comes across Kalista - and recognizes the difference between her and the other denizens of the Shadow Isles. He binds his soul to her, and together they defeat Thresh and free Senna’s soul, but Lucian dies in the process. Senna's confused soul is entrapped by the power of the Shadow Isles, and she comes back as a spectral version of her former self and takes up the Purifier’s weapons. As for in-game, she starts as a wraith of the Shadow Isles - similar to Kalista herself - but slowly the nobility of her spirit returns, and by the time she reaches level 18, she has remembered her original goal once more and decided to continue on her quest as a pure spirit of hope; an almost divine force to purge the darkness from those ensnared by it.

Thanks for reading! Thoughts, feedback, discussion - get to it! :D
