They say you can't go home again.

They're wrong.

The Forest Kingdom has never fully recovered from the long night of the Blue Moon. Chaos has given rise to dangerous and divisive new beliefs. King Harald has been assassinated. And as warring factions plot to gain power, brave men venture into the fearsome depths of the Inverted Cathedral--and descend into the throes of madness. The kingdom's last hope lies with its long-lost heroes--Prince Rupert and Princess Julia....

They're ready for a change, for a new challenge. They're going hack to the land that still haunts their dreams--as the Blue Moon threatens to rise once again....
