A Coilfang Reservoir interior concept.
Coilfang Reservoir is a large artificial lake located in Zangarmarsh. Under the lake is a subterranean pumping station, operated by the sinister Naga. The dungeons are found in this underground area, and consist of gigantic caverns with huge pipes descending from the ceiling powered by titanic crystal capacitors. While the entrance to the reservoir is underwater, the instances themselves are only partially submerged, similar to the Blackfathom Deeps.
Four instances comprise Coilfang Reservoir: three 5-man dungeons and one 25-man raid. Similar to Hellfire Citadel where the dungeons are designed for differing levels, The Slave Pens is designed for levels 61 to 64 and The Underbog is designed for levels 62 to 65, while both the 5-man The Steamvault and the 25-man Serpentshrine Cavern raid are designed for level 70 players.
Official Info
Worldofwarcraft.com says the following about the Coilfang Reservoir:
The delicate ecology of Zangarmarsh has been thrown out of balance. Unnatural phenomena are corrupting and destroying the marsh's native flora and fauna. This disturbance has been traced to the foreboding Coilfang Reservoir. It is rumored that the leader of this mysterious edifice is none other than the infamous Lady Vashj. Only you can discover her nefarious plans and stop them before it's too late. Coilfang Reservoir is divided into four areas, three of which are five-man dungeons (the Slave Pens, the Underbog, and the Steamvault), in addition to the 25-man raid dungeon, Serpentshrine Cavern.
Lore
The aim of the Coilfang Naga is apparently to control the water of Outland, which is becoming a rare commodity on the continent. Although no evidence exists, one theory is that they are attempting to gather enough water to create a new Well of Eternity for Illidan.
