Whose Jhin?

So... after reading theories on "Deadeye" it became more apparent that these 4 champions desire something they want. The name "Jhin" is definitely not an event but it is a name, an incomplete one to be exact. Djhin - or to be exact, a Djinn, a creature that may have inspired the next champion. Some may know the name it other terms like Jinn or Genie to be more precise if one wants to be more local. What people know is that this creature is capable of granting wishes yet there is always a catch in the end.

So "Jhin" here, must have met these 4 champions either being attracted by their personal desire and granting their wishes - but with a catch, a slumber or a dream as seen how they're eyes are closed yet their face is at peace (aside from Zed of course).
