The dungeon inserts a rectangular summer memory into the winter Iowa map and applies different persistence and interaction rules inside it.
Although the surrounding Dallas County terrain was covered in snow before transfer, the trailer rectangle contains established weeds, dry dust, summer flowers, and long-neglected objects. It was captured from another time rather than merely warmed.
At the boundary, a children's bicycle is cut in half while an identical version remains beside the neighboring trailer. A fallen fence has both halves offset, and a minivan is sliced front to back with the winter portion absent.
Loot from inside does not enter the floor's temporary category. It becomes permanent inventory, allowing Carl to retain the motorcycle and yard contents.
After token activation, the system explicitly warns that the zone exists in a different time instance and physical interactions work differently. A countdown delays the actual fight so Carl must witness the recorded interval.
A sharp rectangular patch of summer yard inserted into snowmelt terrain, with objects sliced at the temporal boundary.
The splice lets the dungeon stage a specific pre-collapse event and preserve its objects beyond normal floor rules.
