Álfakirkjan í Tungustapa (Icelandic folklore story)

Описание: quick explenation of the story by Karen:

in short then it's about a man/boy that suddenly disappears on new years eve(it's said that there are lots of parties and stuff among elves on new years eve here) so his brother(arnór, the boy that disappear is named sveinn)
so arnór walks unto tungustapa, then the rock(tungustapi) opens and he hears lots of singing and understand that there is a mess among elves there
then he sees his brother, sveinn, kneeling infor the altar there and a clerk with is hand over him, so arnór understand that they are "vígja" him(probalby into the church or elve society) so he calls to sveinn to come back, or he will die
then sveinn "hrekkur við" and wants to run to his brother but then the elve-priest tells them to lock the church door and punish the human that disrupted them
but sveinn gets to live, but is told that he will kneel down and die the next time he will see the elve-priest
then arnór starts to run away(would be better if I had the story on text but not audio ..) but hears "álfareiðina" following him
then one of the elves say a vísa which ends with so he will not see the light of next day, light of next day and then arnór falls down after running, is really tired and then álfareiðin rides over him and leaves him near death than life
but sveinn lifes on, becomes a munk and sings so well that nobody was as good as him, but he was a bit depressed after what happend
then when his father was old, then sveinn was asked by him to sing in a church near tungustapa, since there he wanted to die.
Then on one part of the messa there came a storm that made the church doors open, then outside there were like open doors into the stapa and out came light, sveinn and the elf-bishop looked into each other eyes, then sveinn and another farmer fell down and died
