Nostalrius Begins - Quality wow vanilla realm (1.12)

I've seen other posts but I can't get it to work.

I'm level 15, have done the Dead Seed questline.
- I've been to Razor Hill's lock trainer
- Ive been to Org and the guy who's suppose to give me the quest is Grayed out
- I've been to the Undercity

I cannot find anyone who gives me a pre-quest!

HELP!
