Walker was finding himself excited. There was something about how Gil couldn't tell what this distant elemental plane was that seemed to latch on to him and take up a lot of his focus. A small whisper of an idea that it might be something he is looking for kept telling him he should push to examine it closer. Push himself to learn more right this second.
There was a little more that he and the others didn't realize. That the mana radiated from a far off elemental plane that Gil could barely feel was resonating with all of them slightly. Just enough that they all felt an interest. Just enough that they were all able to feel what was out there and that they did not know it in the same way as the basic elemental manas.
