OK, done all those. I'll give you a freebie and just add the Regions instead of replacing Underground, though I've had to give it a slightly different name to avoid the issue that cropped up a little while ago (I went for "the Regions of Fairune", hope that's OK). And thanks for reminding me to check that no more worldbuilding tags had snuck into Characters!

PS I'm assuming there's a distinction between "Layla (Fairune)" and "This Layla (Fairune)", but please tell me if I'm wrong.
