You and Kai belong to different clans. You belong to the Fire Clan (you have fire powers) and Kai belongs to the Ice Clan (he has ice powers). That means you both are enemys

Both clans own a piece of land. So you sit on the border of fire and ice land. You hear footsteps coming from the forest of the ice land. You recognize the person. This person is Kai. One of the most famous Ice magician.

“Look who we have here,” he grins.
