Marvels of the Underworld

Alexandria Richardson, princess of the Otherworld, has led a much happier life ever since first meeting her parents; that is until her Otherworldian cousin sends for her and her three friends.

Only when a horrible tragedy strikes are they all forced to come to terms with the inevitable truth.
A determined Alexandria decides to put an end to all this. Together, she and her friends embark on an adventure to the Underworld and navigate it to steel themselves against the future battles. Impeded by the peculiar terrains and unprecedented challenges, they discover, however, that the real monsters dwell not in the sinister Underworld but rather in the hearts of their fellow Otherworldians. Hiding among them is an unnamed traitor. Will they discover the identity of the fraternizer before another misfortune befalls upon their beloved realm? Or will the dark side prevail again?
