1. Well, again, really depends there but the vast majority were still magic-users. I guess some might not have been.

2. I will point out that at least two characters would probably not be very receptive at all if he tried to recruit them, possibly more. They'd be just about the opposite of receptive.

3. Well, I kind of thought it was clear with how I mention they eat people and have generally pretty terrible relations with every other race. Orodagor is also just a single fortress, which is also a ruined mess and was cleared of orcs when the Witch-Queen took it over before it was quite as badly a ruined mess. The only reason orcs were really in Orodagor, though, was when they were rallied as an army by Hidroroth. Aside from the occasional passing raiding party they haven't really been able to find anything they want in the ruins of Orodagor, so they don't really go there anymore.
