But there is no predestiny involved. The Gods cannot control the Exaltations at all. They shards don't even have to go to Lytek. Celestial Exaltations are, by default, outside the purview of the Maidens because if they weren't the Primordials would win the War! Not even the Unconquered Sun can more than affect the Celestial Exaltations a little. Direct control, even in the form of being able to tell who will Exalt, is out of the question.
Think of it like this. You, as a Sidereal, can foretell that I, a mortal, will become the greatest swordfighter in the world. And this will happen because I've got the entire Loom of Fate backing me up. But a Solar can fuck up that fate by, say, taking me as her new boy-toy. The Convocation of Essence-Wielders will then need to reevaluate my Fate and determine a flexible Fate that will, eventually, they hope, lead me to becoming the greatest swordfighter in the world. And the Exalt can fuck up that Fate too.
Now, Exalts are not outside of Fate so their actions are at least somewhat predictable by Sidereal Astrology. But Celestial Exaltations were made to fuck up Fate by their very nature. So even if Malpheas gets tired of the game and orders the Maiden of Endings to kill off Solar A through Fate Manipulation, the Solar can tell Fate to fuck off and die and he can actually do that and succeed! That's what being Exalted means: the power to surpass the odds and be more than anyone else. To be a Hero.
Celestial Exaltations, as far as I can tell, are literally Outside of Fate. The Sidereals can detect the outcome of a Celestial Exaltation because, hey, there is way too much heroic sentiment and inspired dreams around Nexus so there must be a Solar around there. But there is no way to predict who will Exalt and how because the Celestial Exaltation was designed to specifically be immune to Fate manipulation and even direct control.
