What's in a place, for that matter?

It's just just the names of my characters I try to make sound elegant and maybe even musical; it's also the names of the places I create. So far that's only been in the MO, which is set in your typical magical land. The name of the place itself is Caernavon, which is almost (because I initially remembered it wrong) the name of a castle in Gwynedd in Wales called Caernarfon. The names of the provinces within this land all came easily to me, with out any effort I can remember:

"There are twelve Houses -- thirteen, if you include the capital Province of Caernavon city, which many of the nobility do not: Elorian; Voriandrin, which is King Jehain’s House; Dunvaelen; Valerra; Daraganthin; Varlindeyn; Maralandra; Derrivale; Perilandra; Everlayne; Lancashire; and Hessingdon. Perilandra is the largest Province; Varlindeyn the most populous. Elorian is very wealthy thanks to Karadon’s exclusive right to mill the red oak that grows in the Dhaum Woods. Everlayne is the smallest Province, and is between Varlindeyn and Daraganthin -- not an enviable position, believe me."

That's the land being described to Amy as she sets out on her quest, and all of those names sound to me exactly like places should, not people. Am I just used to it after all these years, or did I just happen on names that sound inherently place-like?
