110 boost that just hit 120

this character is a 110 boost, i did nothing but the korrak holiday event and a couple of quests,…where do i find the quest to get to Nazjatar and Mechagon ?

I just wanna get the supposed benthic gear and the quick azerite traits that will hold me over.

Any help appreciated

You might have to do some war campaign stuff first? I’m not totally sure as I’ve never boosted a character and just powerlevelled to 120.
