Rather than spreading creation or transcending it, they revere the cycle that destroys it.
Where do we get this, and is there more of it? http://tvtropes.org/pmwiki/pmwiki.php/Main/EpilepticTrees
And this is how I got the implication:
Second ship, the Pasquiniel, manned by pilot
Illio, was to follow the southern pointing
Waystone; and the third, the Niben, manned
By pilot Topal, was to follow the north-east
Pointing waystone; the orders from the
Crystal Tower, they were to sail forth for
Eighty moons [Looking for Aldmeris] and then return to tell.
...
There were three varieties [of waystones], one that pointed southward, one that pointed northeast, and one that point northwest.
It is not understood how they work, but they seemed attuned to particular lines of power. These are the "waystones" of the fragment, which each of the pilots used to point their craft in the direction they were assigned to go. A ship with a name not mentioned in the fragment took his vessel north-west, towards Thras and Yokuda. The Pasquiniel took the southern waystone, and must have sailed down toward Pyandonea. Topal and his north-east waystone found the mainland of Tamriel.
Given that the fragments only cover places that Topal went to that were or will be Towers, and given that a straight North-East shot from Crystal takes you to the site of Zero Tower, I inference that these waystones went towards Towers or at least the same mythic power that chose their construction sites. Again, North-west(ish) from Crystal takes you past Thras to Yokuda, and South takes you to Pyandonea. We know Yokuda already has/will have a Tower there. What's stopping Pyandonea?
And finally,
For all intents and purposes, there isn't one on Pyandonea. Furthermore, we ain't goin to Pyandonea, so unless the tower that isn't walks, crawls, drills, or swims out of the mists, it'll never serve a function in the conspiracy. To go unnamed is as good as not existing.
Orichalc and Zero and Walk-Brass aren't part of this conspiracy. Walk-Brass is really only a foot-note on why there is a Ninth Divine, a Necromancer's moon, and no dwarves. Zero and Direnni stopped doing anything a long time ago, and Orichalc has about the same potency as a potential tower in Pyandonea. Why are they important? Because knowledge for knowledge's sake is important. Unfortunately.
