Jintha'Alor
Jintha'Alor is the capital city of the Vilebranch Tribe of Forest Trolls in the Hinterlands, built by the Trolls of the Amani Empire. Jintha'Alor is the second largest city of the forest trolls only second to the wondrous Zul'Aman city. Leaders of Jintha'Alor are Vile Priestess Hexx and Hitah'Ya The Keeper. Also there are rumours of an ancient egg of Hakkar the Soulflayer residing in the city...
Quest Guide
Jintha'Alor is what instances would be like if they weren't instanced. It's nice to be able to run away, but watch your back if you're on a PvP server.
Jintha'Alor is built in a series of tiers, each populated by a certain level-range and class mix of Vilebranch trolls. Your objective, in most of the quests undertaken here, is to reach the topmost tier and the altar and important people thereabouts. Others happen along the way, including 
[50] Dark Vessels (loot small, slow-respawning bubbling cauldrons scattered around the tiers), [51] Job Opening: Guard Captain of Revantusk Village (gives a nice reward for melee and hunters), and [50] Separation Anxiety, which involves finding two items on the highest tier. Alliance characters will want to be able to do the chain that eventually gives 
[53] Saving Sharpbeak, which has a popular scripted event at its completion, and both factions will want to run Zul'Farrak to be able to complete 
[50] The Ancient Egg, which leads into Sunken Temple and Lower Blackrock Spire.
For people who are not interested in fighting their way through all the levels it should be noted that there is a quick way to skip the bottom tiers; The hills to the east of the entrance (near the graveyard) allow easy access to a piece of wall about halfway up.
As an important note, two instances have key boss-unlocking events here. These will be the first and pretty much only unlocking quests a player will encounter before high-level endgame instances, so it's strange that one has a very difficult time finding a group for this area.
The Zul'Farrak Mallet
One of the most popular reasons to run through Jintha'Alor isn't a quest. The quest text for Gahz'rilla mentions finding a secret out from the trolls. On ancient tablets, a grey drop from the mobs in that instance, one reads that a sacred mallet must be obtained from the far-off Altar of Zul in the Hinterlands and struck against the altar atop Jintha'Alor. The first part is easy enough, a few elites to kill and the sacred mallet is yours. Once you have battled your way through the fierce trolls, and conquered the small amphitheater with the altar (and Elder Torntusk atop it), you need to stand next to it and use the sacred mallet from your inventory. It will transform into the Mallet of Zul'Farrak, the item with which you bang a gong (and it's on, couldn't help the reference) to summon Gahz'rilla.
Higher-level players will have no problem just running up to the top while mounted. Most of the mobs will stop chasing you once you get there. Everyone else without the epics will have to kill their way to the top. Pulls are usually pretty simple and nice and slow. Just be careful of adds – there are plenty of patrols.
Quests to Get Before Arriving
A fair number of these you can't get before lvl 46. Interestingly, [50+] The Ancient Egg comes after you've already been in ZF. Oh, and one last warning - watch your back on a PVP server at this place. But you already knew that because you're psychic.
