There's a new wormhole location for the Shadowlands generator at 45, 55 in ZM (inside the FT in forge of aFTerlives on the map). Unlock seems to be from doing the 150 fragment WM quest given to you in Oribos.

Which quest exactly?

Might need to relog after completing it for the option to start showing up.

Thanks, yeah a relog was necessary.

It's also account-wide!
