All the clues you will get are from the Sigil of The Red and Green Dragon caches. Cache is not at the posted coordinates.
When you arrive, I only hope the Blue Dragon is either not home, or sleeping very soundly!
A little something about the Blue Dragon:
This dragon prefers arid lands and stormy regions such as coastal areas or tropical isles to make their lair. The Blue Dragon's breath weapon is a bolt of electricity and treasure hordes are made up of gold, gems and jewelry. Their diet is that of meat from large animals such as camels or cattle, but they will also eat snakes and lizards.
