There was a Loki fic where Odin took Loki's magic away and he was put in a coma. All the mages of Asgard went on strike because they all felt the pain, and they took him to Iceland where they set up a new community. The Avengers go and check it out and learn more about Loki. I remember a line that said 'taking a mage's magic away is like reaching in and ripping out all the blood vessels' or something like that.
Anyone know? Thx.
