Reggie had decided to stay behind. He had some kind of plan but wasn't going to share it. Though the others, especailly Nat, tried to talk him out of it, the old ghoul was insistent.
Lyall could no longer wait. They were short of medical supplies, food, ammunition, and he trusted them to move only in the daylight.
Through most of the day they covered the ground that Thing One had scouted. Dry, uneven ground with little if any vegetation. They stayed away from the more fertile valleys although all had come to believe that the Abdominations feared sunlight.
By mid-afternoon they found the tunnel that Thing One had scouted, access to an arms cache. Leaving the others behind Lyall, Cleary and Rama scouted the tunnel to check for abominations.
But there was no sign of them. Instead they found more tunnels leading from the arms cache. Someone else had been here. What they didn't find was Thing One.
Cleary worked the locks on the vault doors, and after a short time got them opened. Unlike vaults, the arms cache was not made to sustain human habitation.
