OUT-43: Aponia

Long before the era of the Two Alicorn Sisters, Equestria was controlled by a cult they called the Church of Time. They would worship the goddess of destruction and time, Akasha. 
At the top of the Church there was the Great Priestess, Aponia. All unicorns put their fate in the Church, blindly believing in this cruel Goddess they were worshipping and her mighty priestess.

But the Priestess worshiped not her Goddess. She and others knew the cult would bring nothing but disaster to the world, for Akasha was cruel and unloving. As scary as it would sound, living without a God, it was a brighter future than living under the hoof of Akasha. In the heart of the Church, they plotted the downfall of their own God. And one day, they all striked. 

Aponia walked up to the balcony of the Great Cathedral for the Spring Solstice Festival Ceremony. She spoke the words from the Great Book of Time as every other year, but she did not stop where she would stop before. She continued to preach about the evil of her Goddess, while the crowd fell silent in shock. She spoke about their grand plan of sealing the Goddesses inside artificially created embryos, as the plan was unraveling somewhere far away. And then she stopped and waited. She knew very well what was going to happen. The crowd stood silent for a while, until they all realized the church had turned against their God. The Church had betrayed them. One voice was enough to set the crowd on fire. They all started to shout and ask her to come down, but she kneeled and started to pray. So they set the church on fire. And it burned to the ground, taking Aponia with it.
