The Plague

The Plague was one of the things which caused the downfall of the Aetherii Collective, and presumably many of the other Ancient Empires, in the times of old long before man even stood upright.

Mention
There have been two mentions of the Plague, one was from an Aetherii message to the Triarii, which simply talked of the Plague alongside the Darkness. Another was found upon an ancient datachip

"And the seers have foretold

Of decay in the cold

That broke upon walls of flesh

Brothers of old

Felt it's breath scold their souls

And broke upon it's dark command"

What is the Plague?
There have been many theories put forwards by the Argutus towards what it is, and some hold that is may not actually be a disease in the traditional sense but might refer to war or hatred. No one is entirely saw what the Plague actually is.
