When young adventurer Laios and his company are attacked and soundly thrashed by a dragon deep in a dungeon, the party loses all its money and provisions. They're eager to get right back to it, but there's just one problem: if they set out with no food or coin to speak of, they're sure to eat it on the way! But Laios comes up with a brilliant idea: "Let's eat the monsters!" Slimes, basilisks, mimics, and even dragons...none are safe from the appetites of these dungeon-crawling gourmands!
With the possibility of starvation as a constant companion, Laios' party continues advancing deeper into the Dungeon. The adventurers have made it to the third floor but only rotting zombies, ghastly spirits, living paintings, and golems await them--all of them absolutely inedible. After coming this far by adapting and learning how to live off the dubious bounties of the Dungeon, how will they manage when even the meanest monster won't make a decent meal?
