Thórvilon has enlisted your help to protect Vartúlin and the Kintai from the encroaching darkness that threatens Imhûlar.
'TBD - Blah!'
A pile of the boundary stones can be found at TBD in Vartúlin.
Thórvilon has asked you to place boundary stones around the edges of Vartúlin.
That should be enough stones to fulfil Thórvilon's request.
Having satisfied Thórvilon's request, you should return to TBD and check on Silirtas in Vartúlin.
Sigileth wants to rejoin the rest of your travelling company at Kûr Anzar, to the TBD of Vartúlin.
You should defeat some of the Dead that lurk at WIGHT CAMP TBD before they threaten the folk that live in Imhûlar.
Sigileth wants you to look at Kûr Anzar from a location to the TBD and determine the situation inside the city.
