Consider joining us at Midgard! We're level 12 as well, with full amenities in castle.
Tribe is a good guild, but if you're looking for something more small scale, you could try out with us. We actually have quite a few husband/wife teams, and your hours seem similar to most of ours. PM Aldaris, Diwi, Nachighaa, Thunderhorn, Sorahyah or Steelhart, and we'd be glad to add you.
And like Cinnie, I(Aldaris) would also be glad to just help with quests, advice etc, regardless of guild.
