Duke Grandfather Unleashes Hell

How does a simple day at the museum turn out so wrong?

One minute, Duke and Lilly are looking at ancient dwarven artifacts, and the next a Demon-Lord from the Pit is laying waste to the whole town.

It's going to take the combined power of all of Capital City's greatest champions to have any chance of stopping him. And even then, it won't be easy.

Can Duke and Lilly save the day? Or will one of them have to make the ultimate sacrifice?
