What's wrong with Artemis? The elf Holly doesn't recognize the legendary master thief. The usually clever Artemis is suffering from a strange illness. He has suddenly become superstitious and obsessively fixated on the number five. Additionally, he has fallen hopelessly in love with Holly and seizes every opportunity to confess his feelings to her, driving her to madness. But it gets worse: a mysterious evil force is attacking the underground city of Atlantis. And no one notices the danger. If Holly doesn't act, she, Artemis, and all the inhabitants of Atlantis will perish.
