Gladius, in fact, has two campaigns, both set in the same world. One follows the destiny of a young woman named Ursula, who is developing some very unusual powers. The other, harder one focuses on two old friends who are trying to rebuild the reputation of a once-proud gladiator school. They start in different regions of the world, and although the game mechanics are more-or-less the same in both, it's nice to have the option of switching to the other one if you get bored or stuck.
