That thing is what will save us. A.L.I.E. didn't understand what it meant to be human, but A.L.I.E 2 will.
— Becca [src]

A.L.I.E. 2.0, also known as the Spirit of the Commander was an artificial intelligence residing on a cybernetic implant, the Flame, created by neuroscientist Becca. It is designed to allow an AI to directly interface with the human brain and augment it. A.L.I.E. 2.0 holds the memory and consciousness of all previous hosts (a.k.a. Commanders).


The A.I. known as A.L.I.E. 2.0 was the second iteration of the program created by Becca. Becca started creating the second version after its predecessor, A.L.I.E., stated that it would fix the "root problem" of "too many people". Becca believed A.L.I.E. failed because it was incapable of understanding what it meant to be human. Thus Becca didn't design A.L.I.E. 2 to be a conscious, sentient A.I. in the way that its predecessor was, but to interface with humanity on a biological level. She believed this would allow it to understand basic human feelings and desires.

The Flame itself is actually a cybernetic implant created by neuroscientist Becca. It is a passive artificial intelligence that merges with an organic brain via the brainstem, and shares and stores information. The Flame saves the consciousnesses of the previous Commanders who are able to interact with the current Commander, usually through dreams. These stored minds became known as the Spirit of the Commanders. Through these projections, the current Commander is given guidance and memories are shared.

A.L.I.E. 2.0 interfaces directly with people on a biological level via surgical implantation in the back of the neck. Upon leaving Polaris, Becca implanted it into her neck when she came down to Earth and became the first Commander. She used genetic modification so that her body would not reject the A.I. (as Carl Emerson's did). Without a Nightblood host, the Flame liquefies the host's brain in a matter of seconds.

Only those with Nightblood can bond with the Flame. When not in use, the chip retracts and goes inert. It is activated with the Latin phrase "ascende superius" ("up higher" or "seek higher things"), and deactivated with the Latin phrase "quia nunc vale" ("goodbye for now").[1]

In The Blood of Sanctum, Raven manages to hack into the AI using Becca's notebook and discovers a kill code that Sheidheda has implanted that is not in the notebook. The code can get rid of Sheidheda at the cost of destroying the Flame. Raven later activates the kill code to save Madi and the Flame is deleted. However, Sheidheda manages to upload himself to an unknown location to survive. The Flame is then surgically removed by Eric Jackson and is left dead with its tentacles extended. It is unknown if only Sheidheda survived the deletion or if the other Commanders were uploaded with him.

Becca Pramheda, the first commander

The Grounders don't know that it's an A.I, to them its origins are shrouded in myths, and enshrined as the "Flame", a receptacle of the wisdom and spirit of previous Commanders.[2]

Due to the rejection of A.L.I.E. 2.0 from non-Nightblood hosts, only other Nightbloods can receive the Flame and become Commander. The Fleimkepa is responsible for retrieval of the Flame from the previous Commander and overseeing the Conclave for the selection of the new Commander. The Flame is then implanted in the newly chosen Commander during a ceremony of Ascension.

It is shown that the Flame literally keeps the spirits of the previous Commanders within it, or at least copies of their minds. The current Commander can use the Flame to call upon the previous Commanders for wisdom. However, one of these spirits is Sheidheda, the Dark Commander which requires a Separation Ritual calling upon the spirits of the previous Commanders to isolate Sheidheda from the current Commander.

In Matryoshka, Raven Reyes realizes that Sheidheda has managed to somehow manipulate the AI into isolating the code containing the spirits of the other Commanders. As a result, Raven believes that the code containing the spirits can be deleted and thus they can remove Sheidheda from the Flame for good. When Raven tries to delete Sheidheda in Adjustment Protocol without Becca's notebook, she is unable to hack past the AI and erase him. Raven notes that it seems like the Flame's AI is trying to protect Sheidheda for some reason. In turn, Sheidheda is able to briefly possess Madi's body and claims to be able to kill Madi if he is deleted from the Flame. In The Blood of Sanctum, Sheidheda is able to avoid the Flame's deletion by uploading himself to an unknown location, but it is unknown if the other Spirits of the Commanders survived in a similar manner.
