Sun Fountains are new innovations by the Empire to satisfy the thirst for arcane energies for High Elves and Blood Elves throughout the Empire. Sun Fountains are essentially, miniature Sunwells. They contain enormous quantities of arcane energies similar to Moonwells. The Sun Fountains are volatile which is why fel energy collectors and arcane crystals are used to maintain their stability. Sun Fountains are also located in areas of heavy population to relieve the need for pilgrims to visit the actual Sunwell itself.
The Empire has only constructed a few of these Sun Fountains, two of which reside on the Isle of Quel'Danas outside the Sunwell Palace of the Emperor. A third is being planned to be built in Silvermoon City itself.
