The Kun-Lai Summit storyline takes place after the Valley of the Four Winds and Krasarang Wilds storylines. Messenger Grummles show up at Stoneplow, Halfhill, and the Grassy Cline offering a message from Lorewalker Cho in the form of the breadcrumb  The Road to Kun-Lai. The summit can be accessed via the Veiled Stair, which begins at the Grassy Cline in the northeast part of Valley of the Four Winds. The Spring Drifter offers a free boat ride through the level 90-infested Ancient Passage, dropping adventurers off at Binan Village in the southeast corner of the summit zone.
Near the end of the Shado-Pan Monastery quest chain, adventurers have  My Husband... in their quest logs, which is a breadcrumb to the Townlong Steppes storyline.
The yaungol invasion and making new allies
At Binan Village, the yaungol are attacking. Lorewalker Cho was able to save Admiral Taylor and General Nazgrim, along with a few other members of either faction's forces. Looking to get the pandaren to ally with them, not the opposite faction, the adventurer's faction commander instructs the adventurer to help evacuees from Eastwind Rest or Westwind Rest.
