Within the game, there exists a model of a generic Hero class found in the training grounds in the later half of the game, and class data for an unused Hero class exists within the game that can be loaded in.

It uses the generic attacks of the 'Mercenary' Class but lacks the animations for it's class action despite having 2 meters for it, suggesting that it was meant to be a promotion for the class rather than Swordmaster being the sole promotion to Mercenary.

War Monk, Dark Flier, and Valkyrie also exist within the game's code, but they're in an extremely unfinished state as they lack a Sprite, Model, Text, and any functional abilities. They do however have Class Stat bonuses assigned to them, hinting that at one point they were considered to be brought back.
