No respawn, no reset, no nothing, leaving Dust behind in the empty caves of the Underground. After some time has past, a mysterious figure decides to research the mountain, shrouded in mystery. When climbing, they make one misstep, falling down the mountain, ending up in the Underground, not knowing they are not alone in the lonely catacombs.
