Well, just to add to my previous post. Now that I'm not a bleary eyed git and can absorb the info like a life leeching sponge, I'd actually like to go with the forest setting.
For some reason, having a bunch of 'civilised' Orcs in a large forestal city really does appeal. It might also having something to do with my druidic, paganistic tendencies... etc!
Oh! And everyone knows a lick of red paint makes fings go fasta!
