As a few people have mentioned, much of the Horde RP does tend to be guild-based, though there have been efforts to revitalise some RP hubs such as the Crossroads.
Guild-wise, depending on what you’re looking for, we could possibly be a fit, as the guild is based on exploration but also has a mercantile branch! Though, we are in practice neutral ICly, but on friendly terms with the Horde.
