Light Shrine
Written by MSG Commander

The Light Shrine is on a peninsula due south of Heiland. (Look for an area surrounded by mountains.)
When you enter the Light Shrine, go due north to get an Ether Energi.
Then follow the path to the west to get an Ether Heal.
Now go back to the entrance and take the path to the east to reach the Light Esper.
And get ready for a big surprise...
Boss Battle
Light Esper
The Light Esper has Heal 5, which restores 3,000 HP, and makes this battle last a lot longer than it should. After the battle, the Light Esper binds her powers to the Astral Ring, and then, she's gone.
Now it's back to the Tower of Espers to eliminate the corrupt energi!
Side Note
Since you're in the neighborhood, after you finish up at the Light Shrine it may be a good time to revisit Heiland if you haven't already. If you talk to everyone in town, you'll learn new details about the fate of Ash's father, Denim. (Plus you can complete Quest 02, and pick up Quest 36.)
Treasure
- Ether Energi - located due north of the entrance.
- Ether Heal - located at the end of the northwest passage.
