The Creation Myth of Scalespiral

Scalespiral has long been known across the multiverse as the ancestral home of the dragons, but no one ever really wonders why. A blue dragon named Sonaranth thinks she might have tracked down a book that holds the answer, though. If only she could get her claws on it, she just might find out how it all began.
Sonaranth has recruited a team of adventures to help her obtain the book for her horde, the Sapphire Library, since she couldn’t possibly leave it to go searching. Unfortunately, as a dragon whose horde is a library instead of a mound of gold, she doesn’t have a huge budget, so she’s only been able to recruit adventurers that are just starting to make a name for themselves. (Level 1 players). She’s sure it’ll be fine, though; how hard could it be to track down and retrieve a single book?
