The core rule book for Immortal: Millennium.
From the back cover:
"It is the end of the modern world. The myths that humanity holds dear are crumbling as ancient gods rise from their secret places to fight a final war with the forces of darkness. A new age of legend is dawning, terrible, magical and breathtaking.
How will you handle the challenge?
An epic new canvas for storytelling, encompassing all of Earth's history and mythology. Play a legendary god, hero, or creature of myth--from Hercules to Venus, from Shiva to the Sphinx. Weild awesome mystical powers against Earth's darkest foes."
Key changes in Millennium:
The die rolled for attributes and skills are now based on the character's ability (d20, d12, d10, d8, d6 and d4) instead of the 1st edition's use of only d10.
The six colors of the halo (attributes) are now replaced by three - Body, Mind and Spirit.
The Prides have been replaced by the Courts.
