Trying to Remember
Was it Jakandor, Isle of (War/Destiny/Legend, depending on which of the three books)? It was an island setting for AD&D 2e where the Celtic/Native American flavoured Knorr did battle with the Egyptian/Aztec Charonti on an island riddled with ruins. Great little mini-campaign-world, but kind of a hard sell for players because you had to get fairly in-depth with the cultures to appreciate it. The Knorr had warrior societies with totem animals like you describe, as Fighter kits.
