YMMV / The Drawing of the Dark

• Fridge Logic: The Ottoman Turks are besieging Vienna with their entire army, including the Janissaries, taken as boys from Christian parents and raised as soldiers for the Sultan. The Grand Vizier of the Ottomans was once Ambrosius' best pupil, and learned everything the old wizard knows. Read the Moral Event Horizon below and consider the losses the Janissaries take in the campaign...
• Moral Event Horizon: There's a ritual Ambrosius could use to ensure victory for the West in the Siege of Vienna. Very simple and 100% effective. What does it involve? Merely the deliberate betrayal and murder of one thousand baptized souls. Oh, and if you use the ritual, you have to keep using it or your... allies, will get a trifle annoyed with you.
