[Lore Suggestion] - Shaco/Nocturne/Fiddlesticks

It has always struck me as odd that these 3 champions didn't get a lore update.

Their old lore stated that they were "Summoned " to runeterra by, well, summoners. Given their strong thematic connections,

Has a fear, is a jungler and has uncertain origins, but is probably not of this world. Has a fear, is a jungler and has uncertain origins, but is probably not of this world. Has a fear, is a jungler and has uncertain origins, but is probably not of this world.

I got thinking, and how about them being given the Vastaya treatment? So, I got to thinking and this is what I came up with:

The sphere of Runeterra is completely surrounded by a realm of fear, a short of "Nether Realm ". Beyond that lies the void, and any void creature that seeks to invade Runeterra has to pass through the "Nether Realm ", and so it acts as a barrier between The Void and Runeterra. That realm is inhabited by "Shadows ", that feed off of the fear of the many races inhabiting Runeterra. Naturally, the "Shadows " converge above every key location:

Demacia, Noxus, Piltover and by extend Zaun, Freljord, Shurima... and act as the source of magic to those regions. Depending on their presence, the nature of magic that they produce as a by-product of their "terror-feast" changes. Demacia has a small amount of light magic because there are very few "Shadows " there, Freljord gets Ice magic because of the climate, how few people there are and superstition, Zaun and Piltover get Hextech/thaumaturgy because of their "science-y" nature, etc etc.

The "Shadows " care very little of Runeterra, as long as they get their fill, but sometimes, the veil between the worlds weakens because too many "Shadows " are present, or a single, very powerful "Shadow " accidentaly reaches too far for nourishment, and then a "_ cross-over_ " happens. The "Shadow " comes through, and learns that it can more effectively feast up close and personal.
