From publisher blurb:
Deep inside a hidden mountain exists a peaceful, magical world of underground caverns filled with colorful oozing slimes, living plants, and a vast array of enchanted creatures. This subterranean paradise was recently corrupted by a mysterious evil creature named Discordia, who appeared from a crack in the depths of the realm, turning the land and its inhabitants into horrible abominations. One lone survivor, an eccentric outcast wyrm named Huffenpuff, managed to escape to the upper level. In a chance encounter with your stalwart group, he explained that his world needs your help. You must retrieve two powerful entities, and if successful, he will gain the courage and power needed to aid you in the final battle against the wicked one. Together, you and this unlikely hero will restore peace and save his mysterious land by undertaking the Fantastic Quest of the Whimsical One!
