Alex along with the members of the yellow flame arrived at the top of the city wall. The city wall was over five hundred meters tall and was as thick as twenty meters. Just strong enough to provide a solid footing for all the mages who had arrived at the top.
The wall stretched out for over a hundred kilometers, even Alex was unable to see its ends. Well, it was curved with three other gates on three different sides, so it was reasonable that he couldn't see its end.
