Unlocking Dark Iron Dwarves

I’m just returning and I’ve unlocked void elf and lightforge dranei but for the life of me the dark iron dwarves are killing me. I cannot get the chasing darkness quest for anything. I’m 4855 with 7th legion I’m honorable with Order of Embers. John Keeshan is fighting for me but in Fort Victory he will not give me any quest. What am I missing. I’m getting close to giving up with this mess again.

Chasing Darkness isn’t a quest in and of itself, but a quest chain. It doesn’t start with Keeshan himself.

Scroll down to the comment section on the wowhead post for some good direction on where to start and what to do for this.
