Spartakus and the Sun Beneath the Sea (1985)

Overview

The Arkadians, a civilization that had endured a devastating cataclysm, found refuge deep within the Earth, where they flourished beneath their artificial sun, The Tehra. However, when the sun began to falter, panic set in. In a desperate bid for salvation, they defied an ancient law and accessed the Forbidden Archives for answers. Harnessing their unique abilities, they created a messenger named Arkana to reach out to the surface. She soon encounters Matt and Rebecca, two everyday kids, alongside Bic and Bac, two peculiar anteaters from Arkadia, and the enigmatic warrior, Spartakus. Together, they embark on a quest through the layered worlds to save their people—and perhaps the planet itself.
