I gave my PC's a magic carpet that isn't anything like Aladdin's.

About 100 years ago, a group of magical people decided that they didn't want human civilization encroaching on themselves and their special places. Their solution was to weave all the people and places into a single carpet.

Anyone who wanted in was allowed, all but one psycho bitch of a mage who strangled her own twins in utero, and later raised them as wraiths.

She stole the rug from the party and has plans to unravel it.

I have a few people and places in mind but I need more filler. I am planning a maze of a city in the middle (called Nonesuch) filled with seemingly random styled houses from all over. Outside Nonesuch, random terrain squashed against other terrain like would never go together outside of here.

Help me fill out the Weave World, please.
