OK, here's some info:

The ENTIRE quest line is first pickup-able @ lvl 54 and starts with https://classicdb.ch/quest=3702
You accept, listen to her story, hand in then get:
https://classicdb.ch/quest=3701
This section is in the Burning steppes and is rather annoying if you are indeed below 54, jsut a heads up. After that return to the woman hand it in then the KING gives you the quest chain here:
https://classicdb.ch/quest=4341
This is where the group part starts and you need to go to BRD. After finding Kharan, you get this part of the chain:
https://classicdb.ch/quest=4342
Head back to the king deliver the news, get to BRD kill the emp, talk to the princess he has under his spell, she'll give you: https://classicdb.ch/quest=4363

Go back to IF hand it in then it's somewhat of a mystery,I believe the king gives these out after all of your effort, hand the quest above in and complete, then open up another speach window with him and he offers them...although it is odd that thottbott has no source for the rings, so it makes me wonder, anyhow I hoped that help with some of the mystery! I'll post once I get the entire thing finished!

((Spoiler alert!))

The Story of Thaurissan:
Hundreds of years ago, the great city of Thaurissan stood proudly in a lush expanse of land that is now the dilapidated Burning Steppes.

Thaurissan was home to the nation of Dark Iron dwarves and at the time, in the midst of a civil war among the dwarven nation at large.

You see, that area of the world was at one point in time part of the Redridge Mountains - until the day that Thaurissan was consumed by a gigantic explosion. The city lay in ruin, the surrounding areas reduced to an ashy wasteland.

That is tragic. How did this happen?

We do not know.

The Dark Irons that did survive made their way into the mountain and began rebuilding their city.

From the ashes of Thaurissan then rose Blackrock Spire and the new Dark Iron nation. Additional fortifications were made within the Searing Gorge, in the area known as the Cauldron.

Stories of an ancient evil that controlled the kingdom of Dark Irons began to circulate.

Interesting, continue please.

Recently, the Dark Irons have been seen on the surface world with greater regularity. Fortresses have been built in the Badlands. Massive exploratory forces have been sent into the depths of Uldaman in search of ancient lore. They have even invaded our own homeland, striking at our dam near the loch.

Unbelievable! How dare they??

We need adventurers to assist us, <player>. Will you help?

Of course I will help!
