Pythian Prophecies

In this dark, alt-history take on ancient Greece, the Oracle of Delphi is not a gift from the gods, but a prison for a powerful, ancient entity. The unwitting daughters of the Pythia are burdened with wielding this terrible magic, saving lives at the cost of others. Choosing who lives and who dies is a heavy weight. Worse, each prophecy manipulates a world where a single choice can affect empires.
