Griar walked and walked for a long time. He had to return to the Peaceful Realm several times during his journey, being unwilling to just disappear for a long period of time. Thus, he never vanished for more than ten hours and would always wait multiple days before traversing back to the other realm.
A man needed to be present for his family, after all–And Griar had an especially large family, not just the one he had started with Flor…
If one only counted the time spent inside this other realm, Griar would have taken about a week to find himself out of the wasteland, stepping into what looked like the remnants of an agricultural field. The pumpkins that had seemingly been growing here had been left behind, not rotting in place.
The Black Moss did not seem to have reached this far just yet, or at least not too greatly… Though that assumption was based on the idea that if it were here, it would have infested the pumpkins.
