This country is dominated by witch covens, who celebrate a holiday every year called "the great feast". Each coven selects 7 witches from their community to participate in a ritual that ends with a lottery. A witch is chosen at random to be sacrificed to Baphomet as an offering. After they are killed, the body is devoured by the other 6 witches. This is the highest honor, as the soul of the witch that is eaten will become one with their deity. Their devotion serving as an example to the community, and being devoured ensures that a part of her strength, will, and power remains within the coven. This ritual is administered by a council, who oversees the preparations and is responsible for carrying out the festivities.
Their are two problems I can see resulting from this. This ritual puts much power in the hands of this council, who lead and oversee the process. It can be a breeding ground for corruption, in which afministrators may see fit to get rid of a rival through this process ( that uppity bitch thinks she's so smart! I have to get rid of her!). A council member may decide to enchant the process, making the random selection less.....random.
The second issue is that a rite like this can lead to discouragement among the masses. Preserving one's life is the greatest instinct. Witches may not be bothered to achieve high ranks or expand the greatness of the coven if they believe that their lives can end with a simple lottery. This cuts back on motivation, leading to stagnation and discontent with the hogher-ups within the coven.
How can I avoid these problems from taking root and make being killed and eaten a worthy honor to aspire to?
