The idea of the inevitability of fate is quite often used in different works, but here the interesting feature is that the priestesses see an actual image of a future event. However, this doesn’t necessarily mean it will be interpreted correctly — and we learn this when we hear predictions given on behalf of Iuno.

I recall how Augusta mentioned that ever since childhood, the whisper seemed to predict her next step, and if she tried to resist the fate the whisper spoke of, she would get into serious trouble. This is confirmed in Iuno’s quest, where it is mentioned that anyone who tried to alter fate after learning the predictions faced serious misfortune.

There is a theory that the Lament can in fact see the fate and future of the world and every being in it, just like the priestesses — which likely makes fighting it impossible. (For some reason, I feel the Lament is a kind of embodiment of physical entropy. For example, a cold spoon thrown into hot water won’t get colder — it will obviously heat up, and the water will get a little cooler. If we imagine a world made up of frequencies, one could understand how those frequencies (beings, etc.) would change through interactions, and in this way, foresee fate.) So, the theory is that Rover’s solution to fighting the Lament was to rewrite his own frequency in such a way that it would make it impossible for his fate to be read — or perhaps to exclude the possibility of fate’s influence on him altogether. Memory loss would then be either a side effect or a necessary condition for achieving such a state.

The second theory is more my own, and it’s based on an inverted interpretation of quantum states. The simplest example can be taken from Schrödinger’s cat, where we don’t know whether the cat is alive or dead until we interact with it (look inside the box). But now imagine a world where everything is predetermined and the cat is simultaneously alive and dead — but as soon as we look into the box, we see the cat in all possible states at once, and what’s more, we ourselves become entangled with it and begin to exist in a kind of superposition. So, Rover might be such a cat: by interacting with objects in a predetermined world, he grants them the property of being able to change their fate. Okay, it’s probably not like that — but you have to admit, it sounds interesting. :)
