The original concept for Myst V was for it to take place 50 years after the events of Uru, but this was retconned in 2006, instead taking place immediately one year after Uru. Everything in the game just looks and is implied to be just so... forgotten. The D'ni cavern is abandoned, as is Tomahna, Atrus seems to have passed away, the now-200-year-old Myst Book is locked shut, stained, and tattered from 200 years of use, and all the ages you visit are equally as empty.
Myst Island. The island is now in a constant rainstorm, machines have rusted over, been removed, or have been bent out of alignment, concrete and stone structures are stained or broken, the electrical power is no longer working, wood has been worn and dirtied, the wooden ship has tipped over onto the dock, the trees are decayed husks, and the grass and weeds are overgrown.
