Álfar, elves, invite us into their hidden treasure

Elves are in folk-lore all over Europe. Why do they overlive (/survive) the dark ages of ignorance? Are they too real to be uprooted? And then: who are they?
In Iceland, the Churchians tried to make them evil.

Our elves are channels into the innermost treasure, pure Being, pure knowledge. We should accept their invitation and never again be conditions.

We can have álfablót (álfa-blót, elves´ blót), to revere our innermost elves and the ones in Nature as well.
