There is one slave up at a time in Nurga. The slave location is -2130, -935, -220 in a pit, not too far west of the zoneline to Frontier Mountains.
The dialog goes like this:
You say, 'Hail, Rinnala Sweetsong'
Rinnala Sweetsong says, 'Hello. Do keep it down. If the goblins see you talking to me I will be punished for sure. It has been such a long time since I've been home. I've nearly forgotten the constant chirping of the birds there.'
You say, 'home'
Rinnala Sweetsong says, 'I used to call my home Firiona Vie but it has been a long time since I have even seen the sun. Perhaps you could help me escape?'
You say, 'escape'
Rinnala Sweetsong says, 'That is wonderful to hear! For me to escape I will need a small iron shackle key, a pouch of supplies, and a strong restorative. The key can be found on a nasty goblin named Pruckib. The supplies can be found on the Taskmaster Yajo. Slave Driver Nimol has the supply of the restorative that keeps us miners going. Be warned, though. I am sure the goblins will try to prevent my escape.'
Upon handing the three items to the slave:
Rinnala Sweetsong says, 'You have done well thus far, now is the time to make my escape. Defend me!'
You gain party experience!
You gain party experience!
An alarm sounds summoning goblins to prevent the enslaved miner from escaping.
A wave of 5 static goblins spawns around the pit where the slave is. When you kill the last of the goblins in the current wave, the next wave spawns immediately. The final wave (#6) includes Mine Overseer Narrik.
You have slain Mine Overseer Narrik!
The mine overseer and his minions have been defeated. An enslaved miner has been successfully freed.
The slave returns to their homeland and a different slave spawns in their place.

Pungub Brawlum says, 'Me home was close to da sea. Came to da Overthere on da Bloated Belly me miss my home can you help Pungub escape from da gobbys?'
