This quest is bugged… Renathal never shows up… countless players waiting days to complete this quest. Please fix this!!
Keeper57. This forum is for issues with the Desktop Launcher (Beta version), not WoW Shadowlands Beta.
The proper place to inquire about Shadowlands Bugs is the WoW Shadowlands forums. https://us.forums.blizzard.com/en/wow/c/in-development/shadowlands-beta-leveling-questing-and-world/250
There are other players with similar issues posting on that forum.
My most humble apologies
