It appeared as a tiny ball of light, then expanded to form a massive ball of bright white light. Then it started to emit dazzling rays, ones that travelled fast and seemed to cover the entire world.
In the eyes of the masters standing close to this behemoth, it felt like this ball was a bomb that got detonated. As for the masters standing away, they saw the giant form a ball, one that turned to be a real star, shining rays of light brightly and blinding all of them.
The light lasted for ten minutes straight. During which, no one could see anything, not even while using spirit sense. Only William was the only one able to see and control the attack.
The minutes that passed slowly on everyone, felt quite boring to most, passed quite fast over William, while he developed small beads of sweat over his forehead.
They might have released their spirit power to the Troll, but William had to control everything, guide such a brutal force and lead it to attack without allies.
