Hello!
What Gobbert says is completely correct, at the end of the Goblin start zone Thrall has mercy on Gallywix after you defeat him in the Ultimate Footbomb Uniform. He sends you with an edict from Thrall to Garrosh which dictates that the Bilgewater Cartel shall remain under the leadership of the ‘reformed’ Trade Prince and shall now work with the Horde.
There are a few guilds which take in Goblins, Hand of Conquest take them as grunts and there are many more mercenary guilds who take them in as their token Goblins.
If you’re looking for an experience more tailored to the Bilgewater Cartel however, I can suggest my guild, which is based off of the Bilgewater military we see in game:
[Goblin/Gnome/N-RP] B.O.O.M.T.E.C. Incorporated - Better Living Through Neutrality!
There is also a more recent Battalion style guild, who are also a group of Battalion/Horde aligned sappers who will give you a truly EXPLOSIVE experience. They don’t have a forum thread yet…
There is also a more trade based guild which has just popped up, the Crankfizzle Caravan which seem to be Steamwheedle/Horde aligned Goblins who carry goods throughout Horde lands:
You may also get a better fix on what’s happening in the Horde Goblin community by joining our discord:
Hope this helps!
