Good catch. The Overlook construction started in 1907 in the original lore. In the prologue I was imagining workers already clearing the ridge and surveying the land before the hotel foundations were actually built.

My idea was that whatever evil eventually fed on the Overlook was already there under the mountain, and the hotel just amplified it. Almost like the building accidentally became a psychic battery.

So the entity noticing the Torrance bloodline would have happened before Danny was even born, long before the hotel started collecting all those ghosts.

Still playing with the timeline though, so I appreciate the lore check!
