Legacy of Madness is a d20 System scenario for 6th- to 8th-level characters. Part of AEG's Adventure Keep line of short, cheap modules in half-sized format (4-1/4"x11"), it is intended to be run as a single session. Intended for use with the Dragons sourcebook. From the back cover:

In the late hours, heroes find themselves quaffing a good drink, eating a hot meal, and reciting great tales of their bold deeds... this is the life that the true adventurer cherishes.

But, when this precious time is cut short by the thunderous bellow of a dragon — one that is hungry for power and thirsty for an unattainable treasure — the true adventurer does not argue.

And when that treasure lies in the heart of a cave where an even more powerful source resides — one that guards the very power that is sought — the true adventurer does not flinch.

And when the treasure bears a power beyond thought, so great that a line of dragons have sworn to defend it — even to the death — the true adventurer asks, when do we leave?

The Legacy of Madness is more than just a myth. For some, it is a way of life.
