I already have may character mostly planned out
A Soldier who was forced to return home after his leg was injured, and he was given a debilitating limp.
He feels that he is a weakling and useless, and that he is a shame to his home and country.
He spends his time drowning his sorrows at the local pub, he sees an opportunity to stop the wolves (or whatever they are) and reclaim some of his pride. (unless he is a wolf, which in that case IDK)
I will change it to adapt to the setting as we learn more about it.
I don't want to ruin the party mood, but I advise you to think why your character is outlawed. I'll provide a number of cases to get you on the way once I've compiled them.
That's the only excuse I came up with so far how to gather a bunch of random Scandinavian Iron Age/Vendel Age people. This violates more than just clan structures and the roles and relations within communities. At least a little justice has to be done to the epoch (and my archaeology at uni lol).
Now regarding your ideas. Most injuries that would make a modern man just limp after medical care, guaranteed almost always a ticket to Valhall or Folkvang. Let's presume he's the one who got away, one way or another.
If he's lamenting and crying each day, that's a sure way to be frowned down at. Being a walking ale barrel, even more so. Being drunk used to be a no no in the North (and it still is, depending on your village in the South). On the other hand the everyday ale was close to small beer. Now I'm sure there were alehouses later on, but I'll have to go and look for earlier examples. Interesting. So keep this in mind and you've already got some things here that get you on the way to indignity.
Thanks for the updates and new signs of interest.
