[@Cyclone], one detail I noticed that you forgot in Ommok's conquest is the urtelem. Urtelem are Galbar's natural buffer against marauding hordes and monstrous beasts. Many hain villages have urtelem herds residing nearby ('taming' urtelem was one of the earliest things Stone Chipper taught the hain). They'd provide some resistance. Although, a herd of urtelem would still be no match for a well-armed ogre warband, so the outcome wouldn't be materially affected.

I may need to change that soon.

Also, White Giants would also fight ogre warbands, but since the White Giants are solitary they would provide less resistance than a whole herd of urtelem.
