According to the plot of Fabular Once upon a Spacetime, the Guardians of the Abyss stole the Sun. The brothers of the heir to the throne disappeared somewhere in the infinite space. The old and feeble king devoted himself completely to the ancient scrolls and stepped aside from the throne. Only a prince can change the fate of a dying kingdom. The player will have to plunge into the magical universe, which is made in the fantasy punk genre. Valiant knights and beautiful robotic ladies live here, for whose hearts warriors fight on armored starships.
