The Genai is device with which all creation is forged. According to myth, the Genai was stolen by a lesser Goddess by name of Tempress. She used the Genai to create her own world which she named after herself. When she was brought to task by the other gods, she was struck a blow so powerful that it also shattered the Genai into many shards which fell to the world with her and littered the lands of Tempress.
These shards are both powerful with magic in their own right and believed by many to be the source of all Arcane power in the lands.
