OK: fair points. So here is a modified development, repeating two paragrpahs of the original to give context:

Chase watches it in action, and notes that humans have developed a means to manage its influence, at least under mild challenge and at a distance. Close to, however, all is overwhelmed. Not humans are, though, utterly vulnerable to its effects. He himself  comes too close and is noticed. The entity, curious, uses Flynn's demonic avatar and its usual tricks to  disrupt social order at the containment facility. Chase escapes, pursued by Flynn, and discovers where he has been held. He meets with familiar local characters, who hide him.

In the middle of this ramshackle hunt, Amicus arrives, having heard of Chase's confinement.  (Chase is tagged so that he can be tracked by the Galactics, separately from  the Parents.) Reunion is punctuated by Chase's horror that his lover, unlike native humans,  is utterly vulnerable to the Darkness, which latches onto his mind. Amicus and Leo are manipulated into confrontation. With great difficult, persuasion and a sharp blow to the head, Chase is able to fight the influence off and get them both off planet.

Amicus had cut and run from negotiations on Khemia, and it is there that they have to return. The flight dynamics also prescribe this trip. During the flight, Chase is subject to an onslaught from rival groups of Monitors, themselves in harsh debate about the Parents and their tactics. What has been learned from the Darkness and Chase's aggressive interactions with it apparently raises fundamental issues. One group fear that Khemia will be contaminated, another fears that the structure in which the Parents themselves exist will need to be sacrificed, a third favours aggressive technological development using the information gleaned. Amicus, still muzzy from his attack on Earth, is directly contacted by rival groups of Parents, which further complicates the flight. Exhausted, they arrive on Khemia to a furious reception from Virginia and the Wolf delegation, and general concern from the Khemians. The truth about recent events leak to Khemia, and from there inot general political debate. A furore begins. 

Ultimately, the opinions of the Wolves do not matter, as Amicus is the only one in direct contact with the Parents. Not so amongst the Kehemians, where interests form into factions, reflection the debate on the flight. Those favouring the Gotterdammerung scenario - the extirpation of the Parents, feeling fear of wider contamination - are fed data on the general manipulative nature of the Parents and their sacrificial behaviour with the Wolves, and they begin to leak this to political effect. This have a strongly religious component to it. They call themselves the Veto.
The Khemian court, represented in negotiations by Neferu, tries to shut this faction down. He is delighted with Chase and his progress and seeks to "weaponise" the knowledge that has been obtained by him. Cue access to the Khemian technology base, with the Veto, which permeates the military and security complex, attempting to hinder every step. Chase, without Amicus but with Neferu, travels to an isolated laboratory in space, funded by the royal family and supposedly loyal. Plugged into Parental equipment in this facility, Chase witnesses a cosmic battle amongst the Monitors. He is able to glean something of the tools that are used, and when he himself is attacked he strikes back with something left smeared on him by the Darkness on Earth. It has cataclysmic effects on his attacker.

From this, the Khemians scientists and he are able to build a toolset, from which to construct "weapons" likely to be able to strike into the domain that the Darkness (and the Monitors, and the Parents, exist.) This has to be kept utterly secret, which - given the mind reading capacity of the Parents - is like not thinking of "hippopotamus" for half an hour. Deep mind control is applied to everyone who accesses the toolset, so that they can only use the toolsin a trance, thinking in symbolic terms about what they are doing, essentially, dreaming their way into engineering.
The Veto find the laboratory and launch an attack on it. Chase and Neferu escape, deeply entranced and imagining themselves to be lovers fleeing a hostile medieval l court to kill a magic beast, but in fact  heading back to Earth to test the tools. The assembly of the toolset is programmed to resemble a lovers' quarrel, which is unhappily broadcast back to Khemia on their arrival. Amicus is broken hearted by the apparent betrayal, and becomes vulnerable to the Veto's attractions. He is to head a fleet that will obliterate the Earth altogether.  

The toolset is successful in destroying the Darkness concentration, but has the effect of stunning the minds of most of the Earth's population. They only begin to recover their wits after a week or so, during which time Chase and Neferu also emerge from their imposed mental state. War in Heaven stops as a result of the successful outcome, but Chase is warned of the impending Veto fleet's arrival. It will take a few tens of years, but the Sun will be caused to explode. The Monitors tell Chase about Amicus and his state of mind, and he and Neferu place themselves at the mercy of the Veto fleet in order to speak with him directly. He refuses to see them, and they are thrown into prison. Scipio is able to intercede with Amicus, building a reconciliation. Chase then enjoys  a perfect reunion with Amicu, and the fleet is disbanded.

What to do with the oddity that is Earth, and how to manage the influence of the Parents are now the prime issues of the day. Earth has already been contacted, and the odd events that it has suffered  and the relief from the nagging pressure of the Darkness on its collective mind primes the species of Earth to accept reality and integrate with the Sapientiae. The broader issue of what has since been called "leaving home", abandoning the oversight of the Parents, becomes a bumpy road for the galactic community.
