Here is a clip from my story The Moment of Glory, available in Ruins Terra:
That first sacrifice was a blood bath. He was adorned with a bright, down cape, his legs and arms decorated with died turkey feathers. He stood at the top of the sacred pyramid and watched as his minions dragged the victims up the steep steps. Some howled in terror, begging for mercy. Others, those who were not cowards, came forward without argument, ready to meet an honourable death.
One by one they were tied to the sacrificial table. With a knife made from the sharpened snout of a swordfish, Montezuma performed the rights. He plunged the blade into their chests and plucked out their still beating hearts, then held them up to the sun, dripping with blood, as an offering. Laying them on tortillas of corn he consumed them, the warm essence of his enemies sinking into his belly.
