stuck with the main quest "dark portal"
 

like the titles say,i has stuck with that quest when required to go to isterreng island but i find no where to receive that damn map.i already google and finding this about the dark cave.But after i checked arround entire map which i could only find the "dark cave" near saw milk in fastland and nowhere to revive the isterreng map.
So i concerned about "is it a bug" or please someone help me.

The map is located in the Temple of Sun (the place where you meet first Valkyrie).

thank you so much for quick reply,i met first valkyrie but there is no entrance or place(where her stand or nearby).could u tell me where is that place or where is is locate.
thank you again.

It should be just on the ground right in the area where you meet her. You don't have to enter anything.

The map looks like a scroll sitting on the ground, and it's located on top of the icy mountain at Vestlig Isle, where you met the Valkyrie.

I've heard from another thread that someone else got stuck because the scroll never spawned. Is that what happened here?

yeah , i has the same problems( i didn't see any kind of "object" near first valkyre) so there is any solution(which relate to cheating or save editor)???.i really want to continue my journey.
Thank you so much.

after checking again,that solution help me.
thank you all whom spending time to help me.
