Ravenholdt
This guild of thieves and assassins welcomes only those of extraordinary prowess into its fold. Sworn rivals of the Syndicate. Ravenholdt is a guild of thieves and assassins which welcomes only those of extraordinary prowess into its fold. They are diametrically opposed to the Syndicate, and are a rogue-only faction as all quests are rogue-only quests. The exception is the quest Junkboxes Needed, which is available to non-rogues, but they would require the help of a rogue to get the items for the quest. Their headquarters, Ravenholdt Manor, is located in Alterac Mountains, but to get there you have to come from the northeast corner of Hillsbrad Foothills.Reputation
All Syndicate humanoids give 1-5 reputation points per kill depending on your current level. As well, there are a few quests that increase your reputation, but your primary method to raise your reputation is from the repeatable quests for turning in pickpocketed items.You start off at 0/3000 Neutral with Ravenholdt, meaning if you kill any Ravenholdt NPCs before raising your reputation by at least 5, you will become Unfriendly and be unable to raise your reputation any higher ever again. To raise your reputation from Neutral to Friendly, the repeatable quest Syndicate Emblems is available. You will have to turn in 11-12 [Syndicate Emblem] and once you are Friendly, this quest is no longer an option. From Neutral to Friendly you can also deliver five [Heavy Junkbox] for Junkboxes Needed.
To raise your reputation beyond Friendly, the only choice is the repeatable quest Junkboxes Needed. There is no known faction reward for obtaining Friendly, Honored, Revered or Exalted, except that the guards speak to you nicer. There is, however, speculation that Exalted may be required for part of the rogue epic quest.
