So I couldn't help but wonder as to why Kyros would forbid entry to the Spires. It seems they were some sort of hubs on those continent spanning road-walls - why not reclaim and rebuild them for faster travel, at the very least?
I think they are somehow connected to the Kyros' power and he\she\it is afraid anyone else will learn of Spires' secrets and rival her rule. Maybe they're some sort of magical magnets that that can be tapped through wall-roads like magic veins? That would certainly explain Kyros' immense magical power.
The only question remains - why Kyros allowed the Fatebinder to claim them all of sudden? It seems that Kyros has plans for the Fatebinder but until devs release a DLC\add-on\sequel there's no way to answer that.
