[X] Gather your kin and kith and go hunt down the source of this evil
-[X] Bring Abjorn, Gabriel, and the Brothers Stig with you and Sten. Offer an invitation to Aki to come along--you got a good example of how helpful a strong Fylgja can be during the Raid, and you've never seen someone with better ability given his age--even if all it can contribute is its eyes in the sky and Aki's own cleverness and sensitivity to more esoteric things, it'll be a boon for tracking the source of the Curse quickly. As for yourself... You know your condition well, you'll come along and do your best to provide ranged and defensive support with your Hugareida rather than immediately charge in, but you won't rule out taking attacks of opportunity if you think you can tilt the scales safely.
-[X] Send a runner to Halfdan's Farm, ask him to protect your home while you're busy investigating this Curse issue, you don't want to leave anything to chance with this kind of sorcery in play.
