Finished the work on my character. 

Basic Summary of Orcs:

-Orcs are not, in fact, nomadic. Rather they do settle down but, due to their nature of infighting for glory, are seen as outsiders by most other races.
-Orcs are not inherently violent nor stupid, rather there are some intelligent enough to match elves while most are similar to humans. Combat is only done for glory and being a bandit is seen as abandoning their traditions.
-Tradition is everything to Orcs, it is what binds them together despite being miles apart from each other. Going against tradition is acceptance of being banished from their societies.

I don't know why but I see the Orcs being a bit chivalrous, though it may be due to my natural tenancy to not want to have Orcs who are simply violent to be violent. Combat is done for glory and the rewards from tournaments held between villages is often a feast and some money. Sort of like competing in a medieval tourney, there are many things to do. Sword fighting, hand-to-hand combat, archery, and some horseback riding. I imagine that Orcs may also be naturals at riding horse due to having formerly been nomads.
