@Faolyn This is what it says about the orcs in the Unapproachable East.
"The Zhent's came to the aid of Thesk against the Tuigan Horde a dozen years ago. After helping to win the battle against the Horde, the Zhents opted to leave their orc units stationed in Thesk. Over the intervening years, hundreds of other orcs and half-orcs have come to join their fellows in
one of the few human nations that has shown the capacity to tolerate their kind."
I found that exact quote on Realmshelp.org. I can't help but notice you left out the second paragraph:
The oligarchs worry that the orc soldiers are still loyal to Zhentil Keep. If this is true, the Zhents could conceivably activate these troops at any time and destroy Thesk from within. For this reason, many of the orcs who came to Telflamm have been relocated, but most have been treated well enough in Thesk to reconsider their loyalties, should the call no arms come once again.
So this very clearly shows that the orcs
had been evil--or at least evil enough that the Thesk were still worried about them--but that they only stopped being evil because of the humans and gnomes of Thesk. Since
detect evil in 3e (when Thesk was last detailed) could detect evil humanoids, it's likely that the Theskans would actually be able to tell.
So no orcs had to be civilized. Other orcs came to live with the humans. Multiple nations in the Forgotten Realms allow orcs. "Few" is more than 2, so at least 3 human nations do so.
And for the umpteenth time, Eberron has non-evil orcs all over the place. It is a another example(beyond the at least 3 above) of orcs that are not evil in 3e.
And for the umpteenth time, Eberron was specifically written to subvert alignments. Keith Baker has strongly implied that he wouldn't have used alignment if he didn't have to (he said that removing alignments wasn't "an option," which to me indicates that if it
had been an option, he may very well have taken it). Using Eberron to indicate that alignments can be changed is utterly ridiculous.
Where are the "three" groups of orcs that aren't evil? You still have shown
one: Thesk. And you are claiming that since other orcs went to Thesk, they must be coming from equally non-evil societies--as opposed to emigrating from evil societies to a non-evil one. Which is far more likely, since you still haven't named any other non-evil orc societies.
Also, "multiple nations allow orcs" is
not "an orc nation that isn't evil." All that does is show that, in the Realms, orcs still need to be "civilized" by other people or they're still Chaotic Evil. Even Obould Many-Arrows is still Chaotic Evil when he
should be changed to
Lawful Evil at least.
