My head hurts.
We're dealing with a time loop within another time loop. Simplify it by realizing that the 'smaller' time loop is essentially predestined by way of being required by the 'larger' time loop, and so could never not have happened. Funnily enough, this means that the Alexander raids themselves are a microcosm of the other time travel elements in the story; G'raha Tia and the Crystal Tower are the equivalent of Quickthinx Allthoughts and Roundrox's journal, while we are the equivalent to Alexander itself.

Or just remember that time travel is an entirely fictional concept that therefore only has to follow the rules that the story itself sets down, and so is only as confusing as the story itself wants to be and overthinking it is pointless. If you need help in understanding that angle, I suggest 'having watched Doctor Who since you were a teenager and therefore realizing that even the biggest time travel fiction around is nonsense'.
