A pencil sketch study of Ost Guruth

On the eleventh page of Fenley's journal, he spent many hours, over the course of the journey back to Bree, secretly sketching a study of Ost Guruth, trying to use a cross-hatching technique he had studied in Odelynne's drawing of Bree. His intent is to ask Odelynne for advice on how it might be improved, and once it's as fine as he can make it, give it to Liffey as a keepsake.
