Bard's place in the lore revamp

Bards are known as storytellers, and his reveal teaser specifically mentions a lot of old lore stories that have been addressed, a lot of fallen kingdoms, disappeared races, and missteps of mankind. In addition to this, his constellation--seen as a sign of his presence--is stated as being absent recently. I wondered then and I wonder now how this might impact the dichotomy of Riot's in-game lore. Let me explain, and I'll see what you think.

First, the League itself is now a disparate, non-existant entity, a fallen institution. In the lore, it was cast off to create more unique champions and situations we could see them in, and I think, on an honest level, it's helped in that regard. You can say what you want about certain plot elements or details that have emerged since, or ones you might miss from the old days, but there's a lot of good here. Champions like Yasuo, Rek'sai, even Bard himself however, have emerged with unique, non-generic lore that doesn't pertain to, in the end, 'being summoned to fight other people for reasons'.

However, it is a fallen institution. Bard's constellation was absent, recently, which means he returned or the equivalent, and he is stated in his reveal to show up to divert Runeterra from a catastrophe. It makes me wonder if he is some sort of wondering spirit with control over stories or the ability to shape the affects of ending societies or to alter mankind's decision... I don't know. It's impossible to say. I doubt if he shows up to literally save the world that roaming, tunneling, and turning things gold is enough.

So maybe there's a tie that could be made, in-lore, that somehow links Bard to the retcon of the League of Legends. That somehow the Institution was headed down a path that would have destroyed Runeterra, and so Bard is responsible for erasing them from history, while still leaving all of the loose ends--champions brought here from other worlds, items, legends, and so forth. I know it's out there, but those are the only theories I enjoy.

Thoughts?
