A small clan in Hisui once concluded that both the Diamond and Pearl clans were wrong, that another god stood behind space and time alike: a white deer. In this, they were in agreement with most world religions, yet they curiously did not distinguish between Wyrdeer and Arceus; the two were the same species in the eyes of the Legend clan. Never a large faction, no traces of this clan exist today, save perhaps in the field of religion and the flutes they used to charm pokemon.
Wyrdeer were therefore treated as a holy pokemon, even by those who prayed to a god they called Sinnoh, and this impression was undoubtedly aided by the reality warping magic of their horns. Encounters with even Stantler today can be life-changing; those with Wyrdeer must have struck those in Hisui who experienced them as a profoundly religious experience.
Perhaps, in a sense, Wyrdeer are creators, connected with the bizarre space-time distortions occasionally recorded in the late Hisui period; perhaps they are not, for every species recorded therein (at least since Porygon's invention) is thoroughly attested in another time or place. If they should be credited with creating anything, perhaps it is their compatriots: the strange, now extinct evolutions of the Hisuian age might have once stared for too long into their horns.
Much has been lost since Hisuian times, including Stantler's method of evolution; Sinnoh's modern population does not cherish deer like the old clans, considering them at most a pokemon fit for riding. But it is a brave soul indeed who rides a Stantler, and no one born into Hisui would ever think of riding a Wyrdeer; only a legendary hero from afar could possibly accomplish such a task without going mad!
