Imagine a land of dark sweltering jungles, filled with nameless monstrosities and savage reptilian head-hunters... Imagine hacking through dense undergrowth to uncover forgotten ruins filled with glittering treasure. Imagine uncovering forgotten temples and the shrines of dead, nameless gods... Imagine running for your life as you awaken what should have been left to rest, the foul cries and screams of repellent horrors champing at your heels...
