From the back of the core rulebook:
Hundreds of Mysterious Civiliztions under Guidance of a Hundred Gods... Immortal Vessels of Divinity... Adversaries Dark, Cruel, and Cunning... Aftermath of an Apocalyptic War... Prelude to The Song of Unmaking...
Body/Armor Hit Locations... innovative Momentum mechanic to swing the tides of battle... Improvisational Magic so you never have to cast spells the same way twice... Attribute/Skill Advancement driven by Roleplaying!... Weapon and Armor Customization... intuitive percentile system to resolve actions dramatically...
'Nuff said. Just grab your weapon and be a hero.
