The jaguar stood at the door of the temple. The smell of blood from within assailed his keen senses. He placed one paw, and then another, over the threshold. The priest walked to the door, as the sun’s light faded, and greeted the warrior Tepiltzin.
The party had driven the beasts to the edge of the cliffs, the kill was swift. Tlilpotonqui smiled broad and warm. It had been a fine day. His smile faded as he spied the crescent Moon already hanging delicately in the sky. The west was fading to pinks and golds. In his excitement, he had forgotten the time. He fell back, letting the party get well ahead, and turned towards the cliffs. As the last rays of the Sun faded he dove towards the rocky waters below…
The party is walking through the forest at night when they come upon a clearing. Half a dozen black-robed corpses lie scattered across the ground, and a pentagram of blood is shoddily drawn in the dirt.
It seems these people summoned something they could not control. Whether or not the demon returns is up to the GM, but it would be just as rich if the demon never returned, and for the rest of the night, every stray sound or odd shadow will be jumped at!
