All the same, if you concede that the term was never used until the so-called development of what is now labelled "Tamrielic" - and here is one myth we may safely rationalize -, your argument that Reman Cyrodiil "did not even call himself Emperor" seems debunked.

Fashion and family resemblances set aside, professor, historical accounts confirm that Reman II was born three decades after his father's death.

...unrecorded erfridder of Unsgrad, and anyone with a passable fluency of Middle Cyro-Norst knows the meaning of the name; to wit, "it was in this darkness that the north wind set out from the lands beyond lost Twil."

The Society was aware that professor Antabolis had handily adjusted his linguistic judgement in the service of Sedur Norilnor, but we had no idea that he would be equally sloppy in other contexts. Historical reconstruction has shown "Emperor' and 'Empress" to have surprisingly dissimilar etymological origins. The former is based on the longer title first taken by Cuhlecain, "Emen Peror Ele" or "First Emissary of the Stars". The latter was, as you have noted, derived from the Cyrodiic "Mother of Man", Auma-Par-Eshe, or Alma-Par-Essi in its oldest Aldmeri form. Folk etymology later transformed that archaic title into a female equivalent of "Emperor", which first appeared in writing during the reign of Uriel II and was well established by the time Kintyra assumed the throne.

While I can already predict your objection to what I am about to propose, I believe it may well be irrelevant whether Hrol's offspring was the product of a god-kings liaison with Alessia-mud or a mad soldier's [censored] of a child -- mythically, they seem to have achieved the same purpose. Ostensibly, this may appear a paradox, but the proof lies in the Amulet of Kings, Chim-el Abadal. As we know from the Daedric Invasion, the Amulet of Kings has such a connection to the royal line that it is able to identify one who is an heir to that line, primarily because anyone who is not of the Septim lineage cannot wear it. Yet witness reports say that Mankar Cameron, the leader of the Daedra-worshipping cult that opened up portals into Mundus in the first place, was indeed able to wear the jewel. Further, the Imperial line itself has been broken and replaced by different families several times -- not the least of which is the huge gap between the Reman Dynasty and that of the Septims, both of whom were able to wear the Amulet. Such evidence has led (most) members of this community to agree, then, that the bond between Tamriel's royalty and the Amulet of Kings is one based on meeting certain mythic prerequisites and fulfilling a particular dualistic mythic archetype (the Enantiomorph), not upon lineage.

Thus, it must be concluded that if the Remans were able to wear the Amulet of Kings, as has been historically attested to, then they (or Hrol, or the Hrol-figure, etc) must have fulfilled this preresquisites -- perhaps, as one early contributor to this discussion noted, through a re-enaction of Akatosh's role in the Creation. In short: credence must be lent to Temple Zero's claim that, at a fundamental level, the Remanada is what you would call a "true" myth -- be it through historical recapitulation of the Enantiomorphic trinity or through later mythopoeia on the part of Talos and his consorts.

I believe they're both devs, making stuff up on the spot.

Of course the Remanada can only be "reliably" dated to the Second Era, when the Imperial University refuses to open its libraries to honest scholarship, and the records of the monastery at Weynon were lost to daedra before they could be properly examined. But the evidence is there, whether Professor Hasphat accepts it or not...

It does not surprise, though it does disappoint, the Temple that our most esteemed opponent continues relentlessly to diminish the House of Cyrodiil. All know of his unfortunate dishonesty in the service of the Hlaalu, but perhaps the street is not aware that since returning to the Province, he has taken as his patron one Casmon Oricoses, a notoriously corrupt bureaucrat who has every motive in the aftermath of the Oblivion Crisis to elevate the uniquely august status of the House of Septim. Even ignoring the ties between Cuhlecain and the Reman dynasty and the questions surrounding his assassination, the Professor's motive in diminishing the former Empire is clearly suspect.

Why do we require Reman Cyrodiil to have special mythic significance? Aside from the obvious need for his successors to retroactively justify their rule over the whole of Tamriel... You might consider their use of the Amulet of Kings to have been justification enough, but as I have said, people like a good story.

Woah, never knew THAT. I have seen them around and to think all this time they've been devs. #$@%

Seen them around? One just registered and the other almost never posts...

If it was truly simply Septim propaganda concerning being able to wear the Amulet, then your point stands, if not (or if the myths may work retroactively to change that truth) then that mythic significance would be required as AP suggested. Besides, how does simple Septim propaganda literally stop somebody from wearing the jewelry (as you may witness in-game), unless the mythic were playing some part?
