Saridor

Saridor, the Ruby Dragon, is the god of the gem dragons. Five gem greatwyrms call themselves a Thane of Saridor and believe themselves responsible for preserving the memory of their long-lost progenitor. These greatwyrms are named Aleithilithos (an amethyst greatwyrm), Hrodel (a crystal greatwyrm), Smargad (an emerald greatwyrm), Charsima (a sapphire greatwyrm), and Tithonnas (a topaz greatwyrm). Each thane is actively seeking out their echoes across the worlds of the Material Plane, hoping to merge with these other dragons, with the goal of eventually uniting themselves to re-form the great Ruby Dragon.
