After the accident with the zombie dogs, Luciel didn't take any further actions in the next few days because all the situation could be solved by Dan's team and the kids.
When Luciel looked at the map that Dan and the others had marked, they were nearly halfway to the north base.
He wasn't familiar with the routes, so he had asked Dan and the others to plan their route back to the north base.
He also asked them to take the shortest route if possible, so even though they were always taking a break in the afternoon because of the weather, they were still able to travel far.
They only needed to travel for another week before they could finally arrive at the north base.
He hadn't visited the space he shared with Treyton since they started traveling, so the only messages he had read were from Treyton—one indicating their location and another saying they had started traveling back to the North Base a day earlier than them.
