Bleucorundum (or Bleu for short) was a sapphire greatwyrm who returned to Quelmar when prophecies began to speak of the return of Sardior. Bleu believed it was their duty in this new world to collect and begin the rites of resurrection that would restore Sardior to life.
About
Bleu had a special psionic connection with the lost god Sardior which manifested as a strange call from beyond this world. She was prepared to answer that call by amassing and collecting the Ruby Court once more.
Lair
Personally, Bleucorundum hoarded histroical artifacts, especially those with any importance related to ancient wars, including prehistoric ones. She believed that most creatures could not be trusted to properly safeguard historically significant artifacts, but she could.
Some of the items included portraits, ancient money, coat of arms, armors, enchanted swords and weapons, old infertile dragon eggs, a dragon chess set, tapestries depicting the ancient battles of The Four Dragons, and a music box that plays the haunting song of Sardior (which sounds a lot like "I Will Wait" by Mumford and Sons).
