Walker wasn't sure what to do with this free time. He had a lot on his mind after he had been pushed to the point of telling every other leader on the Gneiss council that he was done with the conversations and questions. Especially since he had no idea how to ensure that everything went smoothly now.
It would take a lot of time and there was also the fact that they might get a visitor sent by the elemental kings and the dragons within the elemental planes. The odds were actually very high that this would happen sooner than later.
The reason that walker thought this was simply because after they had arrived and the days had passed, there was a notable message about there being a little more mana flowing through the bridge than usual. Some of the more experienced mages waiting there had made a habit out of gauging how much mana they sensed flowing.
