[quote]MCXXV, forthcoming. Recorded by Scribe Ixolt When the great Emperor Calus and his Shadow of Earth had nearly conquered the system, the Leviathan was rocked by a great disturbance. Royal Mechanics reported that, in the inner rooms of the ship, a strange rift had opened, and from it came the acrid stench of Hive ritual pyres. [b][i][u][I am Savathûn, and I am Death!][/u][/i][/b] It was through this rift that Savathûn, the Witch-Queen, allowed her monstrous children to pour into the belly of the great ship and flood its corridors with their clicking and skittering. A great many of the Leviathan's inhabitants were filled with dread and fright. [b][i][u][While this coward invents his histories and futures, I wait.

They’re fanfic. Calus wanted his Psions to predict the future (specifically the Young Wolf’s future). Normally, the Psions can predict some of the most likely future events. But Guardians cannot be predicted because of the Light. So the Psions took what knowledge they had and wrote false predictions (there are parts where it’s clear that the Psions didn’t have accurate information or understanding of the things they were writing about). All these false predictions were made to be the future that Calus wanted. So it is fanfic for Calus, and most of it is very unlikely or impossible and inaccurate, but to Calus it’s the perfect future.
