The Long Knives

Going back to the Valley of Trials is hands down the best full circle experience in WoW since launch back in 2004.

Quest is bugged for orcs created during legion remix, Kaltunk is nowhere to be seen.

This is the questline for the [race=2] Heritage armor.
For this questline you must have an Orc at level 50+ who is exalted with Orgrimmar.
The first quest popped up after login and wants us to meet Eitrigg in Orgrimmar.
