[I’m sharing how I’ve known and interacted with Everyone, starting with the Aesir. The Vanir will be next, then the Rokkr, and then the category where I put those Who don’t seem to pick just one category.]
As with Nanna, I’ve only interacted with Him through the depression [management] prayer set. I use the Invocation to Hoder by Shannon Graves (from His northernpaganism.org shrine) to welcome Him, but that’s really it. No other prayers, no offerings, no holy days, no physical shrine / altar, and He doesn’t have a tumblr tag.
