Recovering the  Branch of Nordrassil requires killing Volcanus in the  Firelands. Cerdia has a very nice comment describing the encounter, which you can view here.

To access the area Volcanus is located in, however, you will need the following:

•  Charged Chitinous Focus
•  Charged Emberstone Focus
•  Charged Rhyolite Focus
•  Charged Pyreshell Focus

_____________________________________________________________________________________________________________________________________________________________
IMPORTANT NOTE: Due to generally being done by raid groups who drastically out-level and out-gear this content, I must heavily emphasize that people will need to go easy on their DPS for the relevant bosses! (This is especially true post-stat squish of Patch 6.0.2.)  Otherwise it will simply be impossible to get this quest done.
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯

First off, let's begin with  Obsidian-Flecked Chitin Fragment from Beth'tilac. This fragment appears when a Cinderweb Drone is killed. The mob will only "drop" one fragment, however, so you will need to kill three of them to be able to form  Dull Chitinous Focus.

 

Once that is done, take a spiderweb "rope" to get to the upper level. Place the item on the web floor for Beth'tilac's  Smoldering Devastation, preferably at the latest moment possible since the object will only persist for two minutes, before jumping down. Once the transition is over, immediately return to the upper level and pick up your  Charged Chitinous Focus before it despawns. IF BETH HAS LOWERED HERSELF TO THE GROUND LEVEL, YOU CANNOT GO BACK UP AND HAVE THUS FAILED TO KEEP THE DPS IN CHECK.  (Alternatively, you may have taken too long to obtain the needed Dull Chitinous Focus.)

Next up is  Emberstone Fragment from Shannox. In order to get the fragments required from this boss, you need to destroy three Crystal Prisons. The quickest way to do this is to have yourself or other raid members purposely step on the Crystal Prison Trap that frequently spawns throughout the fight, then immediately "kill" it to trigger an Emberstone Fragment to appear. THIS CANNOT BE SOLOED UNLESS YOU HAVE A PET.

 

Create  Dull Emberstone Focus once you have what is needed. When Shannox is casting  Hurl Spear, which will trigger a path of fire jets in a swirly shape from the boss, place the Emberstone Focus as close as possible to the area of the fires. Once that special attack is over, pick up your  Charged Emberstone Focus. (Timing on this does matter. See this MMO-C post for why.)

Our third item of business is  Rhyolite Fragment from Lord Rhyolith. It spawns around the edge of the circular area somewhere between every thirty to forty-five seconds or so during the encounter (see Wowhead map for coords). Sounds like an easier time gathering three fragments this time, right? Unfortunately, this is countered by the difficulty in seeing the object so remember to zoom in your camera view. IF SOLOING, you must collect the fragments before Lord Rhyolith transitions or you won't be able to loot due to constantly being interrupted.

 

Use the three fragments to make  Dull Rhyolite Focus. Place the item near as possible to Lord Rhyolith's feet before he uses his  Concussive Stomp. Pick up  Charged Rhyolite Focus. (Note: It does not matter which phase this boss is in since he uses the stomp throughout the entire fight.)

Finally,  Pyreshell Fragment from Alysrazor. Again, I must emphasize to watch your DPS. Alysrazor's abilities and phases are based on her Molten Power (secondary resource), not percentage of health. When she reaches 100 MP, Alysrazor will start at Stage 1 again. I recommend visiting her page on Wowpedia and going over her abilities section.

 

One fragment will appear on the ground from each of the giant Voracious Hatchling eggs that break open. Only two eggs are dropped off in early Stage 1, so the quickest way to do this is to grab the first two fragments and then have the raid wipe to start the fight afresh. Otherwise you will have to wait until the boss has gone through all of her Stages and begins the cycle again.

 

Form  Dull Pyreshell Focus when you have all the three required fragments. Place it under Alysrazor during Stage 4, before she reaches 100 Molten Power and flies back up. Retrieve your  Charged Pyreshell Focus.

Congratulations! You now have all the charged foci that you need to unlock Volcanus' room. Head to (35.7, 35.9) inside the Firelands instance where "The Path of Corruption" sub-zone begins. Follow that path to reach Circle of Thorns portal and use the charged foci on it. Make certain that you are ready, as you will be immediately put into combat when you enter the special area via the portal.

 

Once you've defeated the special encounter and looted the Branch of Nordrassil, return to Kalecgos at Amber Ledge in Borean Tundra.
