I think Bamboo would be a suited guild for you ^_^
We are woe active in the NT castle, but attending is not mandatory. We're pretty casual and laid back, you can level at your own rhythm. If you need information just ask, the guild is active there's always a few members on, and we're friendly too of course.
Irony of fates also woe in alde and are a nice bunch, if you plan to make a baby I'm sure static would love a new member to try to beat us "adults" in the NT castle xD, tri color are mostly nice also, they woe in both trans and non trans as far as I can see.
