Gwathryn believes that Laerdan was taken to Sammath Baul, which is currently being guarded by the brutal Tarkrîp.
'I sent ahead scouts to espy the movements of the Enemy, and I believe that Laerdan may have been taken into Sammath Baul. When the host from Evendim first arrived here, they tarried a short while, but they have since departed. In their stead, a company of Orcs has been brought here to guard Sammath Baul.
'One of my scouts also saw a messenger from Carn Dûm, who entered into a gate-house. When he left that place, he summoned the creature Lozudurkh, and he was called Key-master, and he gave the messenger access into Sammath Baul by the main door. These tidings trouble me, that the brutal Tarkrîp now guard Sammath Baul, for the Krahjarn and Ongbúrz have always been their fiercest fighters, and the most trustworthy and faithful to their cause.
'If you are to enter into Sammath Baul unhindered, you must thin the numbers of Tarkrîp and obtain the door-key. Return to me when you have completed this task, and we will strike at the Enemy as quick as we may.
'I must speak to you a word of caution, go warily! Something is amiss, and I know not what plans Amarthiel has for those who oppose her.'
