* [[Heath]] first contacted a [[Shadow Entity]] during the story of 'The Desolate Guardians'. From here he learned that he was unable to be helped himself, as the [[Shadow Entity]] said allowing it to consume him would be kinder than his current existence. [[Heath]] has apparently subsequently made a deal with the entity, likely offering his consciousness or soul to the entity in exchange for its assistance helping those that [[Heath]] was unable to contact. This came into play in [[Noah Fulmer]]'s story, where the same [[Shadow Entity]] helped awaken both copies of Noah as well as [[Jay]], [[Roger]] and others from their psychic interrogation. As the interrogation involved both psychic and drug-induced components, the party most likely behind this was [[The Black-eyed Army]], who would have hoped to locate the [[Capital Temple]] through any information Noah could offer. [[Heath]] apparently does not expect to remain alive should he deliver on his end of the deal.
=== What is the deal with the [[Key Program]]? Is it software or hardware? Is this connected to The Angel Without a Face series? ===
* The [[Key Program]] seems to be software, housed on one copy of [[Noah Fulmer]]'s mobile phone. In this sense it shares the trait of being software driven sentience, similar to the [[Data Angel]]. Where it differs however is that the [[Data Angel]] was constructed artificial intelligence with a limited set of functional parameters available to it, while the [[Key Program]] is apparently a software version of a [[Brownshirt]] volunteer that permanently altered his form to perform his task as the key program. The [[Data Angel]] also originated from a different plane of existence to humans, and was sent by another entity to build a bridge between the planes, this would suggest they are probably unrelated.
