A fanatic cult of terrorists plans to bring the Heechee's ancient enemy to Earth and purify humanity in a bath of cleansing fire. You must stop them, but you can't do it alone.
The race to stop these madmen catapults you on a journey to new worlds and new adventures and ultimately across the event horizon of a black hole where you discover mankind's last remaining hope for survival--the Heechee Homeworld.
