Thorium Brotherhood
The Thorium Brotherhood are an elite group of craftsmen who can reveal a number of epic recipes if you gain enough faction reputation with them. They are former Dark Iron Dwarves who have left Blackrock Depths to explore (exploit) the world. All players start off at Neutral (0) reputation with them.
* The Thorium Brotherhood have a basecamp in Searing Gorge, Thorium Point (added in Patch 1.5). There are several quests here (levels 48-52), including three repeatable reputation quests.
* Derotain Mudsipper (al) in Gadgetzan is also a member, and gives the Imperial Plate quests for Blacksmiths.
* Lokhtos Darkbargainer (al), in the Grim Guzzler (tavern) in Blackrock Depths, gives quests that raise faction by turning in drops from Molten Core, and is also the vendor for the tradeskill recipes.
* Malyfous Darkhammer (al) in Everlook.
There are recipes for Tailoring and Enchanting, as well as each specialization of Leatherworking and Blacksmithing. Each of the recipes requires some components from the Molten Core.
Gaining Faction 101
This section is meant to gather all faction-gaining info into one place, so people don't need to bother to read through everything else if they don't want to.
Note: The best way to gain points with ANY faction is to do their quests at as low a level as possible. This is, of course, much more time-consuming if you've already reached 60.
* Neutral to Friendly: 3,000 points
* Friendly to Honored: 6,000 points
* Honored to Revered: 12,000 points
* Revered to Exalted: 21,000 points
Thorium Point
Located near the northwest corner of Searing Gorge. There is an alliance flightpath here, which connects to both Ironforge and Morgan's Vigil, Burning Steppes, and a Horde flightpath which connects to Flame Crest, Burning Steppes and Kargath, Badlands. There is a wanted poster and 3 questgivers that assign 7 quests. You get 100 Reputation Points for each of these 7 quests (700 total), if done at an "appropriate level" - but if done at level 60, you get 10 reputation for each (70 total). Note that 6 of these 7 quests can be handed in after reaching honored status with the brotherhood ("What the Flux?" has to be completed before reaching honored, this is explained below).

Important NPCs
Derotain Mudsipper
Derotain Mudsipper is located in Gadgetzan. If your level is high enough (50) and Blacksmithing skill is high enough (265), he will give you the seven recipes for Imperial Plate (http://wow.allakhazam.com/db/itemset.html?setid=321) in exchange for multiple stacks of Thorium Bars.
* Imperial Plate Belt
* Imperial Plate Boots
* Imperial Plate Bracer
* Imperial Plate Chest
* Imperial Plate Helm
* Imperial Plate Leggings
* Imperial Plate Shoulders
The set gives these bonuses as more pieces are worn:
* 2: +100 Armor.
* 4: +28 Attack Power.
* 6: +18 Stamina.
To complete all of the Imperial Plate quests, you will need a total of 270 Thorium bars, or 13.5 stacks (~4.25 faction per thorium bar). No other materials are required for the quests.
You get 100 Reputation points for agreeing to the exchanges and then 150 Reputation points for each plan for a total of 1150 Reputation points.
Lokhtos Darkbargainer
Lokhtos Darkbargainer is found in the Blackrock Depths bar. You can give him different items to receive faction with the Brotherhood.
* Ten Dark Iron Ores for 50 Reputation Points.
* Two Core Leathers for 150 points.
* One Fiery Cores for 200 points.
* One Lava Cores for 200 points.
* One Blood of the Mountain for 200 points.
It is recommended that you do the Thorium Point quests first to get to Honored and then the Imperial Plate Armor quests to get partway to Revered before starting these turnins to Lokhtos.
Of the gifts, Dark Iron Ore can be mined in the Blackrock Depths and Molten Core. As of patch 1.7 Dark Iron Ore will also occasionally appear in the Searing Gorge and the Burning Steppes. The Blood of the Mountain is a rare gem from the same veins. Fiery and Lava Cores drop in the Molten Core. Core Leather can be skinned from level 63 Ancient Core Hounds in the Molten Core, but requires Skinning of 315, attained by having a Finkle's Skinner, which drops in Blackrock Spire from The Beast that can assist by providing +10 Skinning as well as having the +5 skinning enchant on gloves.
At each new level of faction, Lokhtos offers a new set of recipes. These recipes require some combination of the items you can offer him to gain faction.
To reach Friendly faction with the Brotherhood requires 3,000 points. Honored requires another 6,000 points. Revered then takes another 12,000 points. Exalted then takes another 21,000 points.
