The trident had begun to shine. It started to vibrate and cast an image that was sent out to Ash and Kiani. Since the life force of Atlantis was associated with her life force it showed all those dear to Seira that Atlantis was in peril so was Seira's life.
It showed them the locations of the Dark elves that are near them and nearing atlantis since one of the Diadems had been stolen. The oldest key that was given to the old lords of the council was stolen years before Sandro and Seira had to ascend to the throne.
Images were fed to Kiani, Ash and Daniel and the danger was imminent since the scouts of the enemy was near.
