First, after checking Dark Harbor through, there were no specific mentions on inclinations towards arcanists, nor were there any in the Swordlands piece in the IH main book. As a general guideline, you can expect people to react as under the Mystical Power write-up in IH, though specifics vary depending on circumstance and specific spell used.
Next, it seems that you're missing your second Berserker Ability, Einan. The table only lists Extra Berserk Ability, but the actual write-up tells that a beginning Berserker has two abilities. By my understanding, you gain one of Berserk Strength, Berserk Mind or Berserk Speed, and then you get one of your choice that you qualify for.
Kajamba, I hope you're familiar with the changes to the Armiger
here. Don't worry, unless you had meant to focus heavily on Defense feats, all the changes are upgrades.
Then, some character organizatorial matters. Could everybody list their Armor Class as "AC [normal AC value], Active [active bonus to AC], Passive [passive bonus to AC]"? That's the format I'm most accustomed to reading (being the one I use myself).
Also, I'd prefer if you listed your skills so that you first have the skill groups with the ranks in them, then followed by each individual skill in alphabetical order, including those bought as part of skill groups. For example, Gregghor Bearbait's skills line would look like this:
Skills: Athletics 4; Balance +3 (1ranks), Climb +8 (4 ranks), Heal +2 (1 ranks), Hide +3 (1 ranks), Jump +8 (4 ranks), Move Silently +3 (1 ranks), Survival +5 (4 ranks), Swim +8 (4 ranks)
Beyond the order of skills, you can use whatever order and marking style for ranks/total bonus you want.
Also, having at least one character that has some "face" skills is advantageous in the adventure, though not required.
The landmarks and some famous people coming at some point.
