I do not necessarily worship any particular deity, but I honor and include them in my workings.
I tend to associate myself with the Rokkr, Jotun, and some of the Aesir/Vanir. They are all Norse. I would say the main ones I honor most (in order) would encompass: Loki, Hel, Fenrir, Odin, Utgard-Loki, and Mimir.
Considering I am the priestess of a kindred who does dedications specifically for Loki, I know all about him . ;) He is not just a "michief" God. He is the God of chaos, change and things associated with it- both good and bad. The occasional trick is actually a form of offering in our practice, as long as it is in good spirits and light-hearted. Loki is a neat deity.
I don't necessarily worship deities. But I do my best to honour the one's I work with. My main one being Loki. Others being Hel, Odin, Thor, and Isis. There are others I have reverence for. And I'm starting to get into working with more Jotun and other Norse deities.
