Welcome to Urbia!

Welcome to Urbia! It was either this or "Urban Alchemy"; I got that idea from a book titled "Suburban Alchemy". But I didn't really want to use that, even though I like the sound of it and the idea, because most of the idea was the author of the book's (I guess---well, at any rate, it wasn't mine). But, "Urbia", that's all mine, probably with good reason, because it kind of sounds like a burp when you say it, but the thing is, when I got to thinking about it I couldn't help but wonder why we have the word "suburbia" but not "urbia"? I kind of like it; and besides, I'm sick of the word "urban". Muse: What connotations does the word "urban" have?
