From the publisher's website:
Designer Rich Redman takes us to an inside-out crypt. Who, or what, uncovered this forgotten crypt? What lurks inside? Drop this free online adventure into your campaign and find out what happens when the dragon encounter is only the beginning.
This miniadventure can take place in rural areas in your campaign -- just set it where it will work best for your current needs. This is a good side trek scenario: It's easy to insert it into an existing campaign any time the player characters (PCs) are traveling in a hilly region a bit off the beaten track. Alternately, the blue dragon Kyracolides can be the central antagonist in a longer story that you devise. Use the following hooks and rumors to draw the PCs into the encounter.
Suitable for four 7th-level characters.
