Ray and the four others were currently navigating their way through the underground tunnel. It made him think back to when he had first met the Divine being. When a part of Ray was shared with the Divine being, he found out that the Divine being underneath Avrion wasn't complete.
The Crystal was just a fragment of the whole thing. Ray then thought back to the rumours about the Divine being also being underneath Roland academy. If he put these two things together, most likely a part of the Divine being was also located at Roland academy.
That's when Ray decided he needed to finish his business at Avrion academy and start to search the continent for these fragments of the Divine being. Perhaps then he would finally get his answers about what happened to him and what on earth were those visions he saw.
"Do you know where you're going because of those Dragon eyes of yours?" Gary asked.
