The Slave Pens Guide

30-second TL;DR

Adventure Guide says

• Coilfang Reservoir is the name for a naga-dominated compound that lurks under Zangarmarsh's deepest waters.
• The reservoir, punctured throughout by massive open pipes and pistons, seems big enough to house armies - and, yet, its purpose isn't strictly military.
• The Adventure Guide lists 3 encounters: Mennu the Betrayer, Rokmar the Crackler, Quagmirran.

Adventure Guide says

1Mennu the Betrayer

Mennu is one of the Broken, draenei twisted and deformed by demonic energies unleashed by the orcs. When the naga invaded Zangarmarsh, many of these tragic beings desperately attempted to escape the region. Mennu, however, chose a different path to freedom. In exchange for his own life, he betrayed his fellow Broken to the serpentine invaders and agreed to lord over his kin as a slave driver.

2Rokmar the Crackler

Following Draenor's destruction, Rokmar fled into the depths of Zangarmarsh. The energies that had torn the world apart enveloped the behemoth, bolstering its strength and size at the price of constant agony. The naga were awed by Rokmar's ferocity when they first arrived in the region. Rather than kill the beast, they enslaved it and used the creature to subjugate much of Zangarmarsh's indigenous life.

3Quagmirran

Quagmirran was once a ruler of Zangarmarsh's immense fungal giants. He was captured by the naga while wandering the region's serpentine caverns and subjected to excruciating torture. Now this broken being serves his overlords without question, silencing all who oppose the will of Lady Vashj.
