Yes- I apologize, I thought the priestess had properly explained things.

The Lorn Mother, Micia, is the head of the Caelondian and Tazal Pantheon. She's responsible for all of creation. From her, we're born and at the end of our lives we will return to her. Her heart is a brilliantly shining star. Its light guides the soul of the dead to her.

Technically, this is her and Pyth's festival to bring in the harvest and the end of the current year.
