The Worshippers of the Bloodline

The Worshippers of the Bloodline was a virtual representation of one of Kassandra's genetic memories, relived by Layla Hassan through the Portable Animus HR-8.5.

Description
To some, like the Worshippers of the Bloodline, Kosmos lived in the blood of Deimos. To worship Deimos was to worship chaos itself, and all other blood would be the sacrifice they'd offer.
