Input appreciated!
I can actually show you the tree, come to think of it.
I posted it in all its buggy glory a week or so back. [Edit: Wow, it was more like a month back. Doesn't feel that long, oddly enough!] In short, it looks like we're dealing with, just based on how the story of these characters played out in my head as I generated this...
Gwalder: One of the older options. Considerate of his kinsmen and prone to looking out for them, though his skillset is more social than combat-oriented. Could make an interesting deviation from my normal playstyle and force me down the path of a merchant or the like.
Morcan: Hunts raiders in an endless quest to quench his thirst [Edit: Did I type "thirst his desire" at first? I'm clearly up too late...] to avenge his mother. If he's not careful, he might end up a raider himself in the process.
Rakon: Technically speaking, he's probably still alive at the time of game start, just getting on in years. The story there would probably be that, riding his past successes, he's aiming to finally make that final push to put his clan on the "big board", as it were. Make the clan's name one that kings recognize. (Though it'll probably be up to his sons and theirs, I doubt he'll do it in his lifetime.)
The Two Morcans, Part 1: Yeah, remember "in all its buggy glory"? I forgot to name these fellows. Pending names, the first one - the leftmost - really embraces his Sturgian roots and enjoys bathing in the viscera of battle. He's a young firebrand, probably pretty close to the suggestion you made actually! I can see him mellowing with age and experience, but for the time being, he's blind to the big picture and just enjoys showing his enemies that he's a mighty warrior.
The Two Morcans, Part 2: The "younger" twin takes after his father a bit more. He's a little more circumspect and is constantly trying to reign his brother in. While less a warrior, he's a bigger strategist, so he'd make a good pick if I wanted to try really respecting the permadeath system and keep myself back to command more than I dive into the fray.
I could of course start with one of the daughters as well, but for my first character, it's probably best to take my usual method of "start male, it's what I know". Maybe in a future playthrough, though, just to really throw a wrench at my own head.
