A Debeleian gemstone was a mineral used by Debeleians in order to gain powers from the Dark Deities. In contrast with Debeleian bloodstones and talisman, a gem often contained dark energy from the Dark Deities. Also a gemstone included a demon who was gatekeeper of the gem. This artifact empowered a Debeleian but it had horrible consequences when it was opened from a non-Debeleian.
