The raid entrance for this quest can be found by travelling through the underground passages in the Restless Isles. You need to get to Volcano's Mouth where an ancient warforged will let you into the quest.

Getting to Volcano's Mouth can be complicated without the aid of the spell Greater Teleport. If you have access to this, you can get straight to the quest entrance by teleporting from an instance to the Twilight Forge entry on the list (the suggested starting instance is Tempest Spine or The Subterrane, because they are raid areas without pre-requisites), or the raid group could break up into smaller parties to teleport from 6-man instances. If not, then you will need to fight your way there. If you take the Ogre Khan's Skull and the Horrid Golden Figurine with you (found in Ghola-Fan and Shrieking Mines), you can avoid some large fights on the way.

Should you succeed to get to the end, you will gain access to the Titan Awakes raid quest.

Flagging
The Twilight Forge is divided up into five main sections containing puzzles and other challenges. There are many, varied objectives, some required for completion. The puzzles in particular can be tricky, especially for first timers. The most important thing to do if you are new to this quest is listen, watch, learn, and don't be afraid to ask questions.
 * Complete Hiding in Plain Sight (aka. HIPS) to gain access to the Restless Isles.
 * Complete Slavers of the Shrieking Mines and Bring Me the Head of Ghola-Fan! to get the two sigil pieces. Order is not important.
 * Ostler in the Restless Isles repairs the sigil.
 * Reflagging is never required.
 * obj=
 * Discover the secret of the Twilight Forge
 * Navigate the maze-like Factory corridors
 * Lower the barrier field in the Factory
 * Find the levers that unlock the hatches in the Observation Gallery
 * Reunite your party to pass the high-security corridor
 * (Optional) Acquire 6 Purple Medallions
 * (Optional) Acquire 6 Green Medallions
 * (Optional) Acquire 3 Blue Medallions from the sentinel in the Foundry
 * (Optional) Acquire 3 Red Medallions
 * (Optional) Acquire 3 Yellow Medallions
 * (Optional) Kill 50 Runetusk Thrall gunners
 * traps=Fire, Cold, Acid, Slashing, Colored Hallways (without picking up appropriate crystal)
 * misc=

Please note that attempting to go into a colored hallway without having the matching colored crystal will cause hit point damage akin to a damage over time effect, and can result in death. Do this at your own risk!


 * Green puzzle: Reach this room by taking a Green crystal from the first Leering Sentinel. The object is to route the power in such a way to drop bridges and open doors to each successive part of the puzzle, resulting in 1.) allowing access to the Leering Sentinel containing the Yellow/Blue crystals, 2.) opening the path to the Blue hallway, and 3.) gaining access to the switch for one of the black barriers in the high security corridor. The power can be routed through the ceiling, the floor, and the walls of each small room to open the next room needed. It also causes party member to be temporarily "trapped" in certain rooms until they can later be opened by rerouting power to the right places. Oftentimes, especially in shortman groups, Dimension Doors will be provided to prevent being trapped in the rooms, requiring less people to do the puzzle.
 * Purple "Lava Dive" Room: Reach this room by taking a Purple crystal from the first Leering Sentinel. Fight your way through the maze, you will see a blue barrier with 2 switches past it, and a bunch of ogres to fight. Go past this and you will find another small maze with a lava pit. If you stand on the first bridge and look down into the lava (facing north) you will see that you can swim under the floor to the lava to get past the blue. Whatever buffs you can get to mitigate Fire damage, get them before going swimming (Resist Fire, Protection From Energy: Fire, Fire_Shield_(Cold), or items with some sort of Fire resistance on them). Climb up the ladder on the right and pull the small switch to drop the blue barrier. The larger switch disables one of the black barriers in the high security corridor. Fight your way up through to the second level and jump across until you reach the next Leering Sentinel containing the Red/Blue crystals.
 * Red Underwater Puzzle: Reach this puzzle by taking a Red crystal from the Leering Sentinel on the second level of the Purple room, then follow the red hallway next to the sentinel. There will be another large switch in the hallway, pull it to lower yet another black barrier in the high security corridor. At the end of the hallway, pull the valve to open the hatch, and drop down into the water. You will be underwater for quite some time, MAKE SURE YOU HAVE AN UNDERWATER ACTION ITEM. The object in this puzzle is to pull valves to open the gates and progress through the puzzle. This puzzle is made slightly easier with a Rogue or someone that can pick locks manually (Knock spell cannot be cast underwater), but it is possible to do without a lockpick, it just requires collecting keys to reach valves behind locked doors, and a little bit of backtracking. You NEED three people to do this puzzle, as sometimes party member will be trapped behind the gates and will need to pull valves to let the others through. Once you reach the end and pull the main valve (it will have many colored crystals around its base), all party members will be able to leave the puzzle by swimming straight up through holes in the ceiling. You will come out in the large Blue "cooling" room with the Iron Golems.
 * Yellow Lever Room and Blue Room Force Bridges: Reach the Yellow Observation Deck by taking a Yellow crystal from the Leering Sentinel in the Green Puzzle, and the Blue room by taking Blue crystals in both the Green Puzzle and Purple Room. You will need at least 2 people in Yellow to pull the switches to activate the Force bridges in the Blue room. The object is to coordinate switch pulling to create a path to each of the small platforms on the second level of the Blue room, where there are yet more small switches that must be pulled to lower another black barrier in the high security corridor. While the party members in Yellow pull the switches, the party members in the Blue room jump across the lit tiles to attempt to reach the South, East, and North where the smaller switches are located. There is a fourth switch on the West side right next to the high security corridor. Once these switches are pulled, it will also open the hatches in the Yellow room, and those party members can drop through the holes to reach the rest of the party below.
 * High-Security Corridor: Once all the puzzles are complete, your party will reunite at a hallway with 5 colored barriers. These colors correspond to the crystals that were picked up at the Leering Sentinels throughout the quest, so the party members possessing the colors needed will have to walk up to the appropriate barriers to cause them to drop.

UPDATE: As of Mod 9/Update 1, there are now additional black barriers located in the high-security corridor. Five new switches located throughout the Twilight Forge drop these barriers. To recap from the above walkthrough, the location of these switches are as follows:
 * Green Puzzle: In the Top North room (requires Green Puzzle to be completed)
 * Purple Side: Past the blue barrier and before the ramp to the second floor
 * Red Side: One in the red corridor at the bend and the other is tied to the final valve in Red Puzzle (requires Red Puzzle to be completed)
 * Blue Room: Tied to the 4 levers to unlock the Observatory (yellow) hatches (requires Yellow switches to be pulled for Force bridges)

When you finish the quest, DO NOT FINISH OUT. Proceed over another light bridge to a shrine and a chest. There will be an elevator shaft that you use to access the second part, The Titan Awakes.
 * chest=
 * 2 down side paths on the way to the first Leering Sentinel
 * 1 underwater, accessible after completing Red Puzzle. Take the south middle hatch in the Blue room and swim down. True Seeing or Detect Secret Doors is needed to open a false wall to reach the chest.
 * 2 down side paths after high-security corridor, but before Mindflayer.
 * 1 at end shrine
