The Mayan ceremonial dagger had an inscription in the ancient language that read: "Offer thy heart". It's obviously an instruction left by the past inhabitants of this forgotten place, but who would be stupid enough to stab himself in the heart with a rusty old knife found inside a tombstone? After activating my battery pack the dagger shimmers brightly in a cyan light, the creatures are coming, I can hear their steps. 'It's do or die.'
