Onyxia questline in game?

[moenbase]

I know you can enter Onyxia with attunement. But there are people who would like to do it the vanilla way.
I don't get the right quest to pop in Blasted Lands to start the questline for Attunement on Onyxia.

It's the one that ends up with the Drakefire Amulet if I remember correctly.

As far as I can remember,solar smash I also encountered the same situation as you.
