[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.]
Like His brother (Narvi for those who may not know), Vali has a Younger Face and an Older Face. The Younger Face is the start of the mythological cycle which includes His transformation (Dec. 1st is when He switches from Older to Younger). So, from Dec 1st to whenever the July full moon is (since that’s His transformation and switch to being the Older Face), I read a prayer for Him and Narvi then read ten pages of LotR (*). Relevant tumblr tags: Vali, mushrooms, LOTR, n&v [Narvi and Vali], birds of Vali [primarily owls with some other birds of prey]. Because Vali is part of “the Pack”, there’s also some overlap with those general tags: wolves, wolves: pics, werewolves, Wolf mode.
(*) This talked about in more detail in Narvi’s post here.
