In 2E, there was the weird comparison between Destiny/Fate and Samsara. I seem to recall somebody mentioning Samsara got created purely to actually justify the traditional narrative of "destiny" (things that WILL happen, no matter what anyone does, and can't be averted) given that Sidereals' entire schtick seems to be about making destiny their plaything (i.e. things will happen a certain way unless people with access to a specific toolkit alter them so they happen some other way), and then there was the concept of beings outside of Fate such as Infernals, Abyssals, certain demon species. Furthermore, you had demons that could manipulate fate (the Tomescu, who can see fate both in their own deaths or in things that could affect the Yozi in Creation which they alter to fit better with their progenitors plans), and apparently Essence use in and of itself shakes Fate's branches pretty hard, if not as discretely and efficiently as Sid charms, so that Solars and others aren't bound by fate's expectations of them.
So in EX3, what IS fate and destiny? Are there irrevocable destinies written in the stars that actually affect events? Are they only irrevocable so long as you lack the power to change them via essence, Sid charms, Astrology, so on? Are they just "percentile chances" with destiny being a reading of how likely things are, and Sids are mostly just manipulating causality and the likelihood of things happening the way they see it? Do regular mortals have the chance of averting their fates in that million to one chance? How exactly does it all work?
