Forlean Mutants

The Celestial Empire in the First Biverse led by Altus and his followers was perfect in many ways, but that doesn't mean that it wouldn't have quick succession of stragglers who split off from the empire as a whole.

Origin
A small percent of the Empire did not agree with many of Altus' policies and laws of planet Forlea and thus split off in search of other places to live. These dissidents became unwilling to actively rebel against the Empire for they knew it would be a false war in both their efforts to convert any other people to their nonconformism and their numbers. The Empire did not follow up in any actions as Altus knew they were like him and would not want his people to view him committing a sort of cultural treason.

Soon these separatists began using unorthodox, unregulated Cyla practices and skills that otherwise would have been forbidden on any imperial worlds. Things such as creating life by any means, altering genomes, and overall influencing the worlds they inhabited in almost cryptic and cursed ways.

Eventual Downfall
During the late reign of the Empire (close to the First Cataclysm), they began overusing this power and were corrupted by Cyla. Many fell ill to Maniocylic Depression and Cylograde Amnesia following afterwards. Due to this, many separatists became unaware of their actions and were in a zombie-like state. Previous endeavors with the use of gene influence started to affect them in horrid and gruesome ways.

Once they started mutating they could not stop and kept growing. Many individual Forleans merged together in a disgusting fleshy mass which encapsulated entire worlds. Some became dead and with such Cyla energy built up inside of them, large explosions erupted throughout the many solar systems from which they lived.

Any planets with supposed alive Forlean-blobs were blocked off by the Celestial Empire to keep any and all other lifeforms out, in hope that it would not happen to other races if they were to gain access through the source.

What It Meant to Altus and the Future
Altus felt this as a great disturbance in his rule, and felt as if something even bigger could happen if Cyla cannot be controlled. After the First Catacylsm, Krojun rose up to power and became one of the most powerful beings ever.
