Green Fuel Orb

The Orb is the result of the combination of the three mystical weapons of Arturus. It appears to contain green fuel. Mordred used it to power his robot. After The Chosen One and the Princess of Arturus defeated Mordred in his fortress, the orb was used to power the kingdom and fixed into the fountain in the middle of town.

Trivia

 * There was once a glitch in which if you jump up to the orb, your head will appear between the orb and the fountain. This glitch has been fixed.
