Few people here are likely to know much about places and events in Shadowkey. At any rate, it's a tower, but it isn't necessarily a Tower.
My never-written-fanfic theory is that the Eye is the Stone in a mini-tower, a Hist experiment, an attempt to model a Meric Tower on a small scale. I'd concur with those who say building Towers is purely a Meric phemenon... but wasn't there a Tower in Yokuda at one point? And who built Snow-Throat, and why do the Nords (Children of the Sky) regard it as their origin?
Maybe the Hist themselves are Towers, and they reproduce and extend landmass like mangroves (but really, really slowly). :shrug:

Maybe Snow-Throat is a natural Tower, like Red Mountain. Or it could have been built by the Falmer.
