The animus-like device used by Layla Hassan in Assassin's Creed Origins is called the Animus.
In the modern-day sections, Layla is an Abstergo researcher who develops and uses a portable Animus to explore the memories stored in the DNA of historical subjects. Her work gives her access to the lives of Bayek and Aya in Ptolemaic Egypt.
The Animus is a central piece of Assassin's Creed fiction. It allows modern users to relive genetic memories rather than travel physically through time. Earlier games generally show Desmond Miles using Abstergo or Assassin versions of the machine, while Origins presents Layla's independently developed portable model.
The Helix is a separate fictional entertainment platform associated with Abstergo, not the device's generic name. The Bleeding Effect describes a consequence of extended Animus exposure, in which users may begin to acquire skills or memories from ancestors.
