After a human child had messed up everything in the Underground and killed nearly every living thing, the Underground became a secluded and barren place. The few monsters that remained alive hid in the secrets of Waterfall and Hotland, occasionally travelling outside to visit the town and buy groceries.
But Sans did not move from Snowdin. It was this loneliness of the poor town that drove him to find his way to where the Snowman should have been, and it was this loneliness and made him fall off the edge.
