Ok, here's what I'm thinking:

Formed from another - is this part of the next line or does it mean its own thing?
different color and different terrain - in all likelihood refers to Terra
my passage lies lower than before - ???
my maker a man of many reputations - means that the person or object in question was created by somebody. Kuja is a "man" (hehe, couldn't resist) of "many reputations", but I can't remember if he created anything but the black mages (which I've already tried).

EDIT: After reading this, Bran Bal comes to mind, but the answer isn't a place >.<
