i hear the voices when I'm dreaming

Oooh, I can totally see Herald!Erik as a Fetching+Farsight sort (since he can detect metal at long range ---> Farsight); I see no problem with fudging the telekinesis/metallophilia line for a man who can work with such trace amounts as the iron in your blood; looked at on that micro-scale, there's metal in just about everything, from dirt to people and animals to plants to seaawater to any dyed human-made artefact (most dyes required soaking/boiling in metal pots, so surely some of the metal would have got into it, too! And many were fixed with potash, which contains the metal potassium.)
