ISD 17061 - The Black Feast of Akterumu (Aetavanni)

A brutal mass execution held by SYRIANI DORAYAICA, the Pale Elusha (King) of the Cielcin, within the ancient city of Akterumu on the planet Eue. In a grand, orchestrated display meant to unite the scattered clans of the Aetavanni, the captured Sollan vessel TAMERLANE and its crew—members of the elite RED COMPANY, captured at Padmurak—were sacrificed before a vast Cielcin host. Staged as a ritual offering to one of their gods, MIUDANAR THE DREAMER, the event culminated in a public massacre that symbolized the total supremacy of the Cielcin war machine, the utter rejection of peace with mankind, and marked the end of the Red Company as a notorious fighting unit of the Sollan Empire.

“How long has it been since so many were gathered here?” Vati asked its lord and master.

“Twelve and seven generations,” the prince answered its slave. “Not since Araxaika ended the Kinslaying.” Turning to me and switching from its native tongue to mine, the Prophet said, “That was perhaps twenty of your chiliads ago.”

“Millennia?” I asked.

Twenty thousand years. Nineteen generations.
