It is important to remember that the Elves of Germanic tradition were not the faery or pixie creatures by which more recent folklore has interpreted them. The Elves are the spirits of the ancestors who could influence the world of the living, much like the Roman manes. Their name, from Proto-Germanic Albiz, cognate with Latin albus, means White and shining, they are beautiful and radiant.
Under Christianity their negative influence was emphasised, as illness, disease and madness was attributed to elf-shot. Positive outcomes however were held to be under the weaving of Wyrd by the Meotod, God as meter or measurer of fate.
Survive the Jive and Maria Kvilhaug have both arrived at similar conclusions that one of the most fundamental elements in the origins of Hallowe'en is not just the Celtic Samhain, but the Germanic Alfablót (Old English Ælfblōt) where a sacrifice was given to the Elves on the Winterfylleth (winter-fullmoon) of October.
This veneration of the spirits of the dead is a tradition which, as mentioned in Guyenót's article above, has been cut off from us. The honouring of our ancestors and the preservation of our bloodlines is something that is fundamental to the Racial Weltanschauung and thus on Hallowe'en, I believe it is more important than ever to bring this connection to our ancestors back into our lives.
