Idun: I would fight back if I were you, and before they do it might be wise to find Svafa. All I know is that they've been infected with something that has altered their minds. Whether it is permanent I do not know. I also don't know how it is transmitted, it could be an airborn agent which also could mean that you may be infected.

As Odin says in the Hovamal:
"Praise no day 'til evening; no wife 'til on her pyre; no sword 'til tested;
no maid 'til bedded; no ice 'til crossed;
no ale 'til drunk."
