I can definitely recommend Shadow of the Empires.
We put heavy emphasis on troll culture, rituals and social interactions. Most of our plots and storylines are focused and built around our characters, not necessarily around some big bad we have to defeat.
We’re based in Zul’gurub and Stranglethorn Vale. From time to time, we do expeditions into other areas, but they aren’t that common. Most of the time, the RP we do is based in the city around social interactions.
We don’t do any RP-PvP and we do not interact with other guilds, so if a lot of travel and fights is what you’re looking for, probably not the best choice. We’re also both Horde and Alliance hostile.
From the two years I’ve spent in this guild, I have to say that it’s the best I’ve ever been in, and every evening has been loads of fun. The GMs Zelujin and Dahti are amazing and I’m sure you’ll find a new home here for your troll if you decide to join us!
