Although Legacy of Llylgamyn is the third game in the Wizardry series, it was released second for the NES because Knight of Diamonds, the actual second game, was deemed to be too difficult for beginners (though it was, eventually, released for the NES as well).
Here, the object of the quest, the Orb of Earithin, mysteriously appears in a shop by way of a lost battle and a glitch involving the occasional result thereof of causing a character to be lost in the dungeon, bringing the quest to a close impossibly quickly.
