Hello.
I have a character, death knight and I can’t travel to Shadowlands. In Stormwind is no portal to Oribos and the quest don’t show me where to go. I already talk to Chromie but still no portal. How can I travel back to The Maw?
Can someone please help me?
Simplest solution would be to ask a mage for an Oribos portal.
The portal in the mage tower will not be there if youve never done the shadowlands introductory questline on at least one character of the faction your dk is.
Thank you so much.
I did a part of quest with death knight but now I can t come back to Shadowlands. 
I hope I can find a mage. Thank you again! <3
You have to talk with Darion Mograine in Stormwind (he’s standing in front of the Keep) and complete the SL/Maw introduction quest line. I think you can skip it if you have done it before even as Horde.
Once you’ve chosen your path after arriving in Oribos (play the campaign or threads of fate aka world quests) the Orbibos portal in the portal room should become functional, but only for that character.
It makes no sense and should have been patched out (or at least become optional) when DF released but here we are.
