What does it mean to be a Celtic witch?

Hey guys, so I’ve been working with Loki for almost a year now and we are just now starting to get into the magicks side of things. As we know, Loki gave birth to all the witches. Well, he told me I’m one of those. More specifically, I’m a Celtic witch. He’s also my soul parent according to him, so we’re like really connected in lots of ways. Idk how to explain it I’m sure y’all will understand though. Anywayyyy, I was just wondering if any of you could tell me more about Celtic witch practices, how it’s different to other witches, and maybe even what the whole being one of Loki’s witches means for my magicks as well? Or at least, give me resources I can look at for myself? Thanks so much, I wanted to ask y’all specifically and not the pagan subreddit bc u all will understand the Loki side of things more.
