Glowing orbs that cast a dim but usable light
Glow Orbs provide a dim light for a 5" radius which lasts for 8 hours. Once the orb ‘expires’ it requires a 12 hour rest and then can be shaken to re-activate.
On Ninigurien these were often found in ruins and ancient temples, as well as old cairns or ancient graves. They were rare, but not so rare to be unknown.
Now, far more easily obtained, the Glow Orbs are bio chemical reactions held in a strong synthetic orb which are – effectively – infinitely reusable.
