Thanks, glad you like it! POC/Lurulu was a really surprising story, wasn't it.

There is already a map of Lyonesse, of course, in the books. If it's not of good enough quality for you (which, let's be honest, it really isn't), you might refer to this one -- http://lyonesse.free.fr/lyonesse.jpg -- from Men In Cheese's Lyonesse RPG, a tome I was lucky enough to acquire on eBay.fr and whose many many maps I drool over. Sorry, I can't scan them, as I don't care to break the paperback binding. That same site has posted the Dahaut map, too.

There are tons of Vance maps on the webz, if you're patient enough to google them up. Most are from foreign sites (lots of French). Example: http://membres.multimania.fr/jackvan...dragon_map.jpg

I understand that the Vance Integral Edition (VIE) has lots of new maps never before seen. I've subscribed to the Compact edition (CVIE), but I haven't got them yet. The VIE also released a Graphics Volume that has some maps in it. All of these are quite pricey, though.
