Dreams

Throughout the show, the four boys chosen to be the Tenkai Knights, Guren, Ceylan, Chooki and Toxsa could be sleeping in their bed when their core brick starts to glow. Then, they will have a fateful dream that usually means something is about to happen on Quarton. Also, if their core brick starts to glow when they are not being summoned, they might have a vision. So far, every Knight has had a dream or vision except Chooki.
