Shadow Labyrinth

The Shadow Labyrinth is one of four instances in Auchindoun. It is occupied almost entirely by orcs and demons from the Burning Legion, such as felguards and shivarras. The instance comes to an end with a confrontation against the essence of sound, Murmur. The entry is granted from the south end of Auchindoun. The minimum required level to enter is 65.

Background
It is said that long ago, a shadowy cult invaded Auchindoun. In its depths, the cult released an immensely powerful, malevolent being from arcane captivity, blasting the decrepit city apart. Any adventurers brave enough to enter the abandoned, bone-littered remains of Auchindoun would do well to remember the warning of the city's original guardians, the Auchenai: those who do not respect the dead...... may become entombed along with them.

Dungeon Journal
The original exiles on Draenor found death to be an unsettling and unfortunate consequence of life, and so the draenei hid their dead away in the subterranean grave-city of Auchindoun, a labyrinthine marvel beneath the forests of Terokkar.

Bosses

 * Hellmawicon.png Ambassador Hellmaw – is kept banished by a number of Shadow Council minions in the second large room in the Shadow Labyrinth.  Defeating the last group of banishers frees him.  He has an area-effect fear with about a 40-yard range, and a nature-based venom spit that also reduces armor.
 * Incitericon.png Blackheart the Inciter – his primary special ability is "incite chaos," which is like a mind control on all party members, who then fight each other using all available cooldowns.
 * Vorpilicon.png Grandmaster Vorpil – calls for aid when attacked, causing voidwalkers to spawn at an increasing rate. The voidwalkers move slowly to Vorpil, and when they reach him heal him and damage the party.  Many consider Vorpil the most difficult boss of this instance in normal mode. In Heroic, he also has a banish ability.
 * Achievement Boss Murmur.png Murmur – is a powerful sound-based elemental that has been summoned by the Shadow Council, who seem to be having trouble keeping him under control. Murmur does not move in combat; his special abilities include a sonic boom area-damage effect, a spell that causes an explosion centered on a target player character, and when no player characters are in melee range, a debuff increasing vulnerability to nature damage. In heroic mode, he also has an ability that causes damage to those outside the range of his sonic boom, and the explosion effect teleports all players to the target.
