Alright, i did some work, and i feel like we oughtta stick mmore to fantasy vikings, cuz it gives a bit more leeway. I would give them a high beard and other hair tendency - they live in the cold, so body hair keeps you a bit warmer. The beard is a must. I would also say that you should make them have primarily pale skin and green eyes. They should be raiders AND traders - is it possible to make them not farm? They should have a NATURAL fishing skill, its very important, as Vikings - and Icedwellers as a result - had very infertile land, so they HAD to raid to feed their families, but they were known to trade, and fishing was, of course, a very common trade among them. So the arrival of icedwellers either signifies an attack on your fortress, or a bunch of dudes trying to sell you weapons and fish. They culturally value martial and skill prowess, knowledge isnt such a high priority when you have difficulty even survivng, so it generally won't be too high on their priorities, they appreciate sacrifice, they find politeness and ettiquite unimportant, they have a high tendency to make merry, love AND hate - they make great friends, and awful enemies, and if you screw them over, they have a high tendency to revenge. They are not CRUEL - they expect that Hel will handle all of the torment. They wear leather armor primarily, because where they live, plate would get too cold - they need thick hides, and leather is an appropriate type of wear for them. They might wear metal helmets, if they can have leather underneath. They also should have Steel weapons - as raiders, they need to equip themselves well. I would actually also give them a slightly higher move speed - they run in quickly with a lightweight Steel Bearded Axe and go in for the kill. They also believe in justice, and are rather adventurous. Tamed beasts should include giant wolves, which raiders have been known to ride, and they should build villages as their settlements. Also they mature faster than others - since it is difficult living in the frozen wastes, everyone needs to help, even those which other civs might consider children have been forced to become mature faster, and even 9 year olds are considered adults, with adult responsibilities as warriors and such. Trading should, as i said, include steel weapons, fish, and leather armor.
