Proudmoore's parley bug

so i accepted the quest, got the starting dialog and i am not able to talk to greymane and the quest is not in my log anymore after accepting it and i do not have the ability to continue the story quests. help

There isn’t a direct followup to the quest. It’s basically leading you back to the scouting board to choose a new zone. From wowhead comments, it looks like if you’ve got the Naz’jatar starter quest you have to do that intro to get the phasing right to turn Proudmoore’s Parley in.
