@RokkuHoshiAgain, the specialisation section is for Combat, Stealth, or Magic. Whichever of the 3 your character specialises in is what goes there.
Expert hunting: Why? How? Who taught him to become an expert at such a young age? It's not like he had to hunt to provide for himself or family at a young age.
Sneak, Security, Speechcraft: Why? He has no need or mention of stealth skills in his backstory.
Smithing: Once again, no mention of smithing in his backstory. Shouldn't be a skill.
Still haven't said why parents left Black Marsh? If the father secured the job before leaving, please state so. Taking your family on the road in the hopes of securing a job is just foolhardy.
His father soon became highly respected when he advised the Jarl on a conversation he'd overheard between the woman and a redgaurd visiter. He'd heard about the Alik'r and had never trusted them. The Jarl took his advice and refused the redguards to search the hold for someone.This has obviously been taken from the Skyrim quest
"In My Time of Need", in which Alik'r are searching for the redguard Saadia. Once again, this is not a valid excuse for Jan-Hei's father to gain trust with the Jarl. Chances are he wouldn't even be allowed into the hold, what with the prejudices against beast races that most Nords seem to have. Saying to the guards that he witnessed an Alik'r warrior questioning a woman wouldn't bring up any risks that would allow him to speak to the Jarl personally. You need to come up with a believable - and original - reason for why Jan-Hei's father became advisor to the Jarl, or you'll have to remove it from his backstory.
"When he was old enough, he told his father he wanted to travel to the other holds"How old exactly was he? Everything that occurs after this in his backstory seems very squashed together; he travels for 3 years, joins the guards, is "slow to rise in the ranks" but then becomes the Jarl's personal bodyguard, and then even more "years pass". From gaining enough fame in the guards to be in the Jarl's own guard makes me think he must have been there for easily more than 6 years, especially if he was slow rising through the ranks. That would leave him 19 at the most when he got back from his travels, and 16 when he left Riften. A child of 16 would not survive for 3 years, by himself, with very little training in protecting himself in the wilds; nor would I imagine his father letting him do so.
"Wondering what in Oblivion had happened, he began searching for survivors, clues as to what happened, and a local smithery. It didn't take too long for him to catch a trail of multiple people. Thinking of the possible survivors, he began following them quickly, hoping to catch up to them soon."As mentioned before, Jan-Hei will already be at the base camp by the time the gate is closed and the group start their journey to leave. Additionally, even if they had left, there are already survivors at Kvatch; a number of civilians and guards make up the base camp, that is not that hard to find. As for Jan-Hei's responsibilities, I can't see why he would linger with a group just to close gates when he has a Jarl to protect back in Skyrim. This needs to be addressed.
Again, he's carrying way too much money. Cut it down by at least 200 septims.
