The message returned quickly, and after half a day's sorting by Madame Lin and the high-level members of the Tri-Saint Society, three conclusions were reached.
First, it is not just people in remote areas who forget Durin's identity, but almost all non-power users forget about Durin.
This means that even in the Foresty Land, mortals have forgotten Durin's existence, let alone in the Northern Kingdom and Sidney Union.
Second, the higher one's realm, the less likely they are to forget Durin.
This can be seen by the fact that the Legendary Lord on Elf Island still remembers who Durin is.
Third, as long as one has frequent contact with Durin, they will not forget his existence.
This can be verified through the military academy Durin established. There are not many power users in the academy, but many mortals, yet they all remember Durin's existence.
