Possible updates:
Should 19 be a little further north, the Dwarf and apple are on a bridge, and that dark area north of where 19 shows now, might be it. Also, just to the right when you start there is a Grig village if you jump the stream. No cat harness though....
The first time I went, I turned the wrong way and
I went round and round in a circle for quite a long time. I think I met the griggs four times.
