source: Mya's plot is what actually happened 20 years before.
fiction 1: After that lupa was stuck in a loop of winning the agon (solo), and being controlled to get into the central hub and releasing the dark tide, causing her to eventually die every time, the fiction. Each time the source and fiction merged more, with mya replacing lupa and becoming more real.
fiction 2: After lupa releases the dark tide in one of those loops, carthetyia appears and finds her, but it's too late and lupa dies again (but she leaves the seed so she can meet rover). Carthetyia finds the lab and the incubator who was being merged with lupa but it escapes, she then finds christoforo and interrupts his process of merging the story, resetting it to the original state.
fiction 3: Rover appears at the start of the new reset story, and they replay the story up to destroying the central hub. At the end he breaks the connection between mya and lupa (imperator's authority) freeing her, and entrusts her with the story as he holds back the powered threnodian through the loops.
fiction 4: Then lupa free from the story is able to rewrite the story, she goes to where carthetyia said the incubator should be, and she taunts mya to fight till the end (which prevented a repeat of leviathan escaping). With the story solved, the script ended and fiction merged with reality and they all met again.

Carthetyia PV is a separate thing as far as I understand.
