Bard Missed the Tradgedy of The Shadow Isles

So I hear Bard goes around prevent great catastrophes from happening. Such as when he took the stone away from the Noxian's to be grasp( Hinting that the Noxian Invasion was retconned in a single vid. Nice Job tho)

So When King Anonymous made his decision about attempting to revive a loved one, where was bard?

As i see it, when the old Ionian used the power of that stone, Bard flew and quickly took it from him and hid it away. Couldn't he had ult the Ritual that was crackking open the barrier between life and death? Then hid the mages away or something? Maybe. Im not sure what he could have did. But we're talking mass murder here. The Shadow Isles had a kingdom on it. Many hundreds lived there. Did Bard not hear the---well.........

It make sense that he reacted due to the power of that stone......But if he was just happening to watch over the Shadow Isles that day....wouldn't he had been able to stop it? His lore states that he prevents certain things from happening due to watch he sees in the Future.(Or fom what Jaredan told us)

So I come to this point, Also, that he is in no way like the former IoW. He can't stop everything(He's only one being) So it's not how like the Iow intervening everything. Although, i still wonder if he was able to stop things like The Shurima Fall, or the Watchers. It's probably why those Tragedies are seen in the constellations. In the Teaser, the Ionians were told of those stories probably to show the things that still happened even though there's a being like bard.

Well, Nice Job Narrative
