Fiddlesticks

Fiddlesticks once had a necklace with a key that was stolen by Zoe. https://nexus.leagueoflegends.com/en-us/2017/12/ask-riot-ping-and-a-stolen-key/

There also is a theory that he hung himself, maybe even because he lost his key, which is depicted in the rope he has in his new splash art that replaces the key necklace.
