Does anyone know where it is? I've spent like the last hour or two trying to find it, but I can't! UESP says that its (far)east of Morthal and that the stone steps up to it are by Stonemills, but for the life of me, I can't find it.

Spoiler:
need to be level 20 travel anywhere ie riverwood and a courier will give you message this how he begins

Thanks. So I can't just travel to where he is?
