Zoe's stolen key
recently in an ask riot, this was said about the key "The key Zoe carries around was actually “borrowed” from another champion; you’ll notice it’s missing from his updated splash art."
So, who was it? I thought that this thread would be a good way to start the discussion. Now when I first thought of keys in splash arts, I thought thresh, unfortunately he still has his two keys.
Note the "his" though, and although it may not be his current splash, one of 
's old splash arts has a very similar looking key

In the same ask riot they also have this to say "As to what it opens? Probably best we never find out… " so I'll put my bets on fiddle's key to be the one zoe is carrying, after all riot likes referencing old things/items in newer champs, like heart of gold being referenced by 
But post other possible candidates down below. I wanna see who it is likely to be.
It has been confirmed, its fiddles key, this post is now useless
It has a lot to do with me being a lore fanatic and fiddle main since season 1. I thought his epithet and powers were strangely similar to Zoe's even though they couldn't look more different and like the idea of there being some bizarre connection or moment between these two otherworldly forces of nature. I hope one day we get to hear that story.
There are some of us that will never forget Istvaan :P
