Abaddon

Abaddon is an evil creature who appears throughout the Land of Elyon Series in many forms, including a metallic electric sea monster in Stargazer.

He and Elyon are rivaling enemies. Elyon tries to keep His Land safe, while Abaddon tries to harm and destroy.

Abaddon is ultimately destroyed at the end of Stargazer when a fraction of one of the Five Stone Pillars falls on him.
