Kai did not fully understand the world he was in, and knew that those people in there did. After he tried the invisisbility twice he finally gave up. He sighed and leaned against the wall and slid down "I should follow them..." he said "Maybe then i can get back home... no chance of them letting me go with them if i asked... i will show them holy magicks are wothless against a dark fire mage..." He started chanting a simple fir spell and casted hi power against a building. once the building had caught fire, he smirked and hid, waiting for them to check out where the smoke was coming from. Then he could run and follow the people who tried to explain everything to him.
