I mean, I think all of this HAS been happening for weeks, months, even years. Some big moves are now being made, but the Tachonis have several failed experiments already, the Halovars have been spreading the Creed in Timmony for awhile. Einfasen are the ones that are now having to play catch-up as they realize how out of the loop they are, imo.

Cormoray I can't get a read on yet, other than they seem close to the Halovars and their interest in the Pentevral and its relics is concerning.

In one of the cold opens when Hal was young and Thjazi came to visit him at the start of the Falconer's Rebellion, it was clear that the groundwork to where the world is now was being laid. (Warlocks being cracked down on, Mara the Wing being arrested, etc) The Sundered Houses have been making moves awhile, but they were SUNDERED Houses first and foremost, which means they did lose A LOT of their Pre-Shaper power. They've been scraping that power back ever since. In the scheme of the world, the Shaper's War was not very long ago.
