From the publisher's Web site:
Ashan is a world of legendary peoples. Proud Elves guard the emerald forests of Irollan... Mighty Knights rule the fiefs of the Griffin Empire... Studious Wizards survey the oasis-strewn deserts of the Silver Cities... The grim Necromancers worship in the wastelands of Heresh
and the ravenous demons immured in Sheogh, their prison world.
During certain lunar eclipses the walls of Sheogh weaken and demons burst forth, plunging Ashan into war. And since the dawn of times, the demons legions have been repelled by the allies thanks to a powerful artifact known as the Blade of Binding.
Once again the armies of Sheogh are coming and the Blade will be wielded...
