Humans have two origins, the noble and the mage.
Early in production, they were going to have an Avvar fighter who I believe came from the Kocari Wilds, or the Winterlands, or one of those deep south areas around Ostagar. They cut it due to the time and budget difficulty in coming up with creative designs, and I think integrating it into the plot.
They were also going to have a human commoner origin, where you were raised in Redcliffe, had to sell your sister into marriage to make money for the family, and were in hot water with Dwyn. He would have been the villain for your origin as Vaughan is the city elf, Baraht is to the dwarf commoner, etc. However, again, they had to cut it due to time and budget, and I think because they felt it was already too similar to the city elf and dwarf commoner. (The whole "poor family forced to sell the sister to a guy with money and being pushed around by a greedy loanshark dwarf with a mean streak" is pretty much the exact same story as the dwarf commoner origin, just a different setting.) It got cut later in production, so there's still scraps in the toolset and so forth, and obviously leftover characters like Dwyn being the town jerkwad with the greatest means to fight and biggest refusal to help.
