My player's going to the arctic north to meet with the Mammoth Lords when they gather at the beginning of spring. This meeting, based on the Viking Thing, is used to resolve differences between clans, plan the upcoming warm season, have men and women of different clans meeting to promote genetic diversity, and to deal with the outside world. The PC desires the Vikings to go on raids against slavers and the Cheliax, whom they supply. Cheliax is there to prevent this and even to get the Vikings to raid the PC's home islands. They sent a disguised Erinyes as their ambassador, with a fake ambassador as window-dressing.
So, I'm going to need your help creating interesting NPCs for her to meet and create allies out of. (More on plot and setting below.) What I need:
An experienced guide for their various missions.
Merchants or someone who sells to outlanders.
Petty Chieftains to persuade.
A chieftain charmed by the Erinyes.
Some shamans.
1-3 very important persons.
The emphasis should be on a memorable RP quirk, a problem to be resolved, a complication, and a reason why they might vote to go raiding for either side.
Additional elements to play with: mammoths, white dragons, and skalds
