I dislike using the word "worship" for my practice, so I will use the word "honor" instead.
I honor a handful of God/desses, as well as some wights and ancestors- as is common in my tradition. The main deities, or the ones I honor most, are Loki, Hel, Fenrir, Vidar. Past that, I do honor some of the Aesir/Vanir, the Rokkr and then wights, such as land-spirits. I call myself a Lokean, because I view Loki as a "patron deity" of sorts, and in that sense Hel would be my "Goddess".
I have always had a deep interest in the Northern deities. Some of the ones I honor I began to work with, and devote myself to, simply out of my own personal curiosity about them. Others I felt drawn to, and some even dreamed of, which led me to include them in my workings. When working with these God/desses, everything felt "right" to me, I grew to adore said deities and included them in my workings/devotionals, and that is how I knew I had found the right path for me. :)
