Cave of Rebound Light
A cave known for a lack of entry point for sunlight, but
still remains bright deep inside the cave.
This is caused by the brilliant gems that fill its ceiling,
enabling any light coming from the cave’s mouth to
bounce infinitely inside.
The cave has been noted to be somewhat similar to the Temple of Moss, a temple that existed in the Gaul-Soldat border until around 210AR. Both locales used the concept of certain brilliant gems reflecting even a sliver of light infinitely, causing a normally sealed structure to be unusually bright.
Scholars assume both locations to be the work of an ancient people, though their true purposes are still unknown.
