Sword is an elfin adventurer with pointy teeth and shocking blue hair (very Sega). The "cursed" land he must quest across is divided up into seven different portions, with each corresponding to its own era in history. This means that there is a piece like current Japan, a section like Europe in the 1980s, another like the chivalric middle ages, a space battleship and ancient Africa. All these areas entertainingly interact with each other at the borders. Naturally, the dungeon is Sword's home habitat, generated randomly each time he enters a new one and auto-mapped on-screen so wandering round in boring circles isn't a possibility.
