You, Jiub. Support me on this, pretty please? Isn't Pelinal a Shezarrine?
Hm... I'm not as knowledgeable of the Imperial mythology (the Nine Divines and so on), but here's my best guess. According to the Song of Pelinal, Kyne (who was the widow of Shor, who was in turn the Nordic variant of Lorkhan, who Shezarr is also a variant of) gave Alessia a red diamond (unrelated, I
think, to the Amulet of Kings) that could turn into Pelinal Whitestrake. ("Kyne granted Perrif another symbol, a diamond soaked red with the blood of elves, [whose] facets could [un-sector and form] into a man whose every angle could cut her jailers and a name: PELIN-EL [which is] "The Star-Made Knight" [and he] was arrayed in armor [from the future time].)". The "Star-Made Knight" certainly implies some divine intervention in his creation, so the idea that he is an avatar of a god (Shezarr) seems likely. More misc. quotes from the Song of Pelinal:
"Perrif's falconers had sent for the Nords, and they, looking at him, said that Shor had returned, but he spat at their feet for profaning that name.
"It is a solid truth that Morihaus was the son of Kyne, but whether or not Pelinal was indeed the Shezarrine is best left unsaid (for once Plontinu, who favored the short sword, said it, and that night he was smothered by moths). It is famous, though, that the two talked of each other as family, with Morihaus as the lesser, and that Pelinal loved him and called him nephew, but these could be merely the fancies of immortals."
"[And it is] said that he emerged into the world like a Padomaic, that is, borne by Sithis and all the forces of change therein. Still others, like Fifd of New Teed, say that beneath the Pelinal's star-armor was a chest that gaped open to show no heart, only a red rage shaped diamond-fashion, singing like a mindless dragon, and that this was proof that he was a myth-echo, and that where he trod were shapes of the first urging."
"'O Aka, for our shared madness I do this! I watch you watching me watching back! Umaril dares call us out, for that is how we made him!'" (Direct quote from Pelinal in the same literature)
So the Nords believed him to be a reincarnation of Shor (remember, Shor-->Lorkhan-->Shezarr), he was made by Kyne, Shor's widow, Morihaus referred to him as family, and, most importantly, he himself refers to Akatosh familiarly and implies that he was part of the creation of Mundus. It seems logical that he could be the Shezarrine, but I don't want to be suffocated by a swarm of moths, so I'll leave it at that. Sorry if this doesn't make perfect sense, I wrote it in bits and pieces.
