Now can the Fayth freely travel between Dream Zanarkand and Spira, without Sin's help? Bahamut's Fayth seems to be able to appear there at will, albeit in a noncoporeal form.

The self-contained nature of Zanarkand made me wonder how the Abes could be playing another team, but when I replayed the opening I found out the Abes were playing the Duggles from block C-south. I guess Zanarkand like is New York City, with multiple teams for the same sport.
