Well.
I think a drow settlement could work. blocks ears from the booing with a grin
Unless im misunderstanding this, there was Udos a drow city and there was no where else. We now have Andunor which is massive and diverse, an exciting Goblin Town in the pipeline. I think if it wasn't overly large this would be welcomed by a lot of drow players.
However im more in favour of expanding the Devils Table, ive run and helped run the table. Had numerous drow factions ive been a apart of and even run myself. The problem we have is once the inevitable drow group comes in thats pvp centric. we lose the district and then are hunted into oblivion. This for me is normality. Im fine with it. Ive learned this is the drow way of life if your lolthite. We roll and move on. However giving the drow someplace else in the UD to retreat too would be fantastic.
I know this isn't a popular response to such a question of drow expanision but I felt I had to put my own point out there if only to counteract the overwhelming negative response to such an idea.
