Glowing gems

The Fishwives encountered several unusual gemstones, which glowed faintly when in proximity to one another.

Known Gems

The Marquis' ruby necklace
Ilabrar's blue pearl ring, given to him by his mother.
Cheeky's topaz runic staff
Sathul's dark orb, unique among the known gems because it seemed to absorb light when in the presence of other gems rather than radiate it
Ka-Ess' Matron's Egg, a magical artefact once held by the lizardfolk and the central jewel of his Bone Crown.
