We're a bit of a... strange sort, when it comes to our holiday. As such, we mostly just commemorate the Winter Solstice. Unfortunately, we cannot celebrate this year- we can't travel with our altar- but it typically involves burning pillar candles and Dragon's Blood, and giving our best wishes.
Nothing special to it.
(The rabbit pictured is Aubrey, our alter who also follows Freya; she has nothing to do with the celebration.)
