Purpose
To block entry to the sealed chamber, presumably to contain either experimental radiation or the Marshal’s prisoners.
Significance
The first physical indication of the Marshal’s experiments with radiation, reinforcing the survivors’ growing understanding that the Overlords’ control extends underground and that their ostensive aid hides more sinister designs.
