On a quite new character, I had to do some of the old campaign quests (2/9) until helping to free the Runecarver's arm. I got The First Move when I turned in The Weak Link and returned to Oribos.
You can talk to Highlord Bolvar Fordragon instead of [npc=177136] to skip until Korthia.
When I skipped it, I immediately got Call of the Primus. Talk to Tal-Inara in Oribos to start the questline for Zereth Mortis.
She also offers a skip, I've you have done the campaign with an alt before. You'll start there with 3/7 chapters of Secrets of the First Ones and unlocked world quests.
Beware that you will miss the rewards of the first three chapters, if you skip them.
Edit: With the Hotfix for March 18th, players who skip the Zereth Mortis story will get the reputation with the Enlightened.
