A little further on there was a door on the right. He prepared for the fight, shield and spear ready to act. Ikky opened the door tensely, alert with his senses focused on any threat... and what was behind it disappointed him, no monsters, no physical evidence, it was a damn puzzle or so it seemed.
On the wall on the other side of the room there were 13 gems in the shape of a circle, and a central gem, of the thirteen he could see how only 8 of them, the ones that corresponded to the cores he had activated, shone, the other six were empty, opaque, between the gems. Between the circle and the central gem there was a series of runes, circuits, some linked the gems together, others continued through a succession of runes. In the end that circuit ended in the central gem.
