The Mayan ceremonial dagger bore an inscription in the ancient language that read: "Offer thy heart." Clearly, it was an instruction left by the past inhabitants of this forgotten place. But who would be foolish enough to stab themselves in the heart with a rusty old knife found inside a tombstone?
After activating my battery pack, the dagger glowed brightly in a cyan light. The creatures are approaching; I can hear their footsteps.
It's now or never.
