I was recently going over shadowkey's storyline and came across another tower. the twilight tower I believe or soemthing like that http://www.imperial-library.info/tsosk/summary.shtml heres a page with a picture. anyways is that one of the towers already mentioned? if so snow throat? or is it a different tower or not one at all?
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.
im not sure if it was discussed, but i do think its a distinct possibility. mayhaps the Hist in general are it? the Eye oughta play a part as well... feh, im tired and likely to be sprouting nonesence, so i'll leave this for now.
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:
