I am new to Paganism and I would like an altar within my house now I have moved to my own place .However, I keep striking a problem as what I believe my patron goddess to be is Bast (Egyptian) and the goddesses and path that I mainly work with now is the Celtic Pagan traditions as my heritage is Scottish.

I know Bast would not like to share an altar spot with Rhiannon and nor would I expect her to, so I’m struggling with how to respect her properly and create a Celtic Fae earth altar as well..any ideas please on how I can do this respectfully cause shes given me a lot of gifts in the past that I still use and want to do her justice.
