The grand mapping hall had gotten enough answers from Su and Walker combined. but even more from Walker since he had been the one to remain there until Remey had shown up. So, he didn't feel bad at all having to leave and see what the progress was on another project.
He also felt that Remey had come to get him because she was frustrated with Ignus and his responsibility more so than to actually see the progress on the project.
He was surprised that the greenhouse being worked on in the floating island and elemental dome project was for light mana. The idea fit very well with the materials that they had brought back from the elemental plane's outer territory. It fit a little too perfectly in a way.
