I have recently become interested in. My ancestry is Germanic and Celtic.

The problem is, I am finding it really hard to choose what to do. I feel a very strong connection with the God Thor, yet at the same time i feel a stronger connection with the celtic gods overall.

All of this is making me feel really confused and I’m scared to do anything wrong in case I offend some gods that I have no intended to.
