Delicious in Dungeon

The knight Laios sets out with a skilled party to claim the treasure of a lost kingdom buried deep beneath the graveyard of a small village. Unfortunately, they were bested by a Flame Dragon, who ate Laios's little sister, Farin. Although the party managed to teleport out of the dungeon, they left their equipment behind and were penniless. Demoralized, the party broke up. Now Laios must tackle the dungeon again, and with only one month to save Farin before she is digested.
