The only thoughts I really had were of having my character's clan live in a fairly forested area close to the mountains and they do a lot of mining and hunting. Because of their limited water supplies and due to the fact that the land isn't ideal for farming, they have to trade with other clans for fish and crops. The weather is usually fairly cold and rainy and they're used to wearing heavy furs and leathers. I was also thinking of having them worship a single higher being. Loyalty and honor is hugely important to them and they're fairly proud people which makes seeking help from others difficult for them. They used to be well known for their military prowess and their secure location at the mountains had always seemed to keep them strong until they were overrun by the barbarians and it became their downfall. They were trapped against the mountains and because the lack of conflict had lessened their need for a large, strong army, the majority of their people were slaughtered and those that could escape had no choice but to abandon their home and run for their lives. 

For my character, I had wanted to make her fairly headstrong. She's completely devoted to her people and will do whatever it takes to ensure they're safe and strong, even if that means doing some not necessarily nice things to get there. She can be manipulative and prideful but her heart is in the right place. She likely wont be too pleased with the arrangement of the marriage but she'll do her best to work the situation to her advantage. 

Obviously I have a lot to work on and come up with a good history, but these are a few things I had in mind. That being said, if anyone feels like anything I've mentioned doesn't work or will clash with their own ideas, just let me know and I'll change it :)

I'll also be away all day tomorrow so I won't get a chance to work much more on this until Sunday. Hope that's alright and sorry if I'm slowing things down. 

Looking forward to creating this world with you all :D
