[x] [Raiders] "Pick up your bows! Draw and Loose!" Leave none alive.
I don't think that we'd get them all because it's hard to 100% mop up an opposing group on foreign territory while we're distracted with our saved captives and all. Nevertheless, this would leave them further weakened and survivors will have quite the tell to tale about what awaits those who would mess with our tribe.
[x] [Hero] Focus on Detection (Expand Wolfpacks)
Our biggest problem here was that we caught by surprise in the sudden attack; when we got the drop on them, they were devastated. If our wolves can provide early warning of a hostile presence then that gives us time to assemble our forces against them and to devise a decent plan. Plus, wolves are substantially more mobile than fortifications.
All that said and done, I do think that the wrestling tradition is very cool and of course population would not hurt.
[x] Study Travel (Wonderful World bonus) - Invest time in learning how most effectively to travel. The world is harsh and strange, learning how to traverse it will save the People much in effort and food.
Even if we plop down and become sedentary straight away this is still incredibly useful for ex. military campaigns that we might launch.
[x] [Go] East
I'd like to check out the world a bit more now that we've established a little nook in this place. Doesn't hurt to have intelligence on what's up with the surrounding geography and neighbors even if we do settle.
