A sentient race of neural parasites is in a civil war between the Symbiotes, who've used their extensive knowledge of genetic engineering to alter themselves into symbiotes, and the Parasites who think the Symbiotes have made a mockery of their way of life and seek to wipe them out. The Parasites outnumber the Symbiotes massively and have driven them into hiding.
THE ALIENS THEMSELVES:
- Both the parasites and the symbiotes are small, squid-like beings similar in size to the larval stage of D&D Illithids, that can infect any species that has a brain roughly similar in size and shape to a human brain. They burrow into the host's neck and then alter the host's DNA, RNA, and body, resulting in radical internal changes. Externally, the only difference is a small lump on the back of the neck. Basically, they're the weird lovechild of a Goa'uld from Stargate and a D&D Illithid.
- How the control works depends on whether we're dealing with a Symbiote or Parasites. Parasites take over the host's Nervous system, trapping the host in their own body. Symbiotes, on the other hand, have control at the same time the Host does, as the body gives equal importance to commands from the symbiote and commands from the host. Conflicting commands cause the body to simply listen to neither command until the issue is resolved. The Symbiont also intimately shares thoughts, feelings, and memories with the host and vice versa, which means that conflicts are rare, and happen at the speed of thought when they do.
- Some of them grant abilities that both the host and the Symbiont have access to (or just the Parasite, in the case of them), such as gravity manipulation and electromagnetic field manipulation. Don't even ask how they do this, they don't know either, though psionic capabilities may or may not be involved.
- This is not reversible. The symbiont/parasite can abandon the host, but to do so they must do extensive damage to the nervous system and brain in the process, killing them at best and leaving them with massive brain damage at worst. There are surgical procedures that can separate the symbiont without killing the host, but these are incredibly challenging even for the aliens, and still leave the host with brain damage. As a result of this, informed consent where the host knows what they're getting into by agreeing to this and agrees without being coerced or on a whim is essential for Symbiotes.
- The symbiotes and parasites hail from an earth-like world, and thus, due to convergent evolution, they have psychology and thought-processes similar to our own, and feel the same emotions. The only real psychological difference is between us and the Parasites, as they are in casual, shameless disregard of the human (and non-human) rights of other species, and this stems more from their parasitic existence than anything else.
- The parasites exist in what is basically a fascist monarchy, where the royalty use common fascist tactics to maintain the status quo and clamp down on resistance.
- They are highly advanced, having access to masses of molecular nanobots that they call 'programmable matter', FTL, and an intimate understanding of biology and genetic engineeriong.
- Their society has repeatedly dominated and enslaved countless other worlds featuring sentient species, under the justification that this actually constitutes a 'improvement' in their quality of life and is good for them. The resemblance to Proslavery arguments Pre-Civil War is intentional.
- (EDIT) Their economy is built around the Host trade, and this trade works in a roughly similar fashion to the car market.
- They can clone host bodies, but the nobility doesn't want to switch over to them.
In this case, the question is in regards to the last point in the Parasite's society; the nobility doesn't want to clone host bodies, largely to protect the interests of the breeders/hunters who are the most powerful, and whose members make up a sizable chunk of the nobility.
However, this leaves the question of how would they justify this to the general population of parasites and the peoples they've conquered.
Clone bodies do come with certain perks: they are very quick, easy, and cheap to produce, exponentially more so than natural hosts, and can be custom-tailored on birth, thereby compressing the countless generations of selective breeding required to get the natural host you want into a few minutes spent adjusting the embryo's genes before they begin growing. In addition, they don't have consciousness or intellect and thus aren't prone to the tendency of 'natural hosts' to object to their fate, start revolts, and even murder their guards/breeders (or at least try to), and have none of the ethical implications of using natural hosts.
With the countless pros of clone hosts and the numerous cons of natural hosts taken into account, what kind of explanation would the nobility provide for shutting down Clone Body production and killing all clone bodies? Basically, I'm looking for a excuse for the Nobility to outlaw Clones despite the fact that they are at least as good in a given category as a 'natural' host, and oftentimes better. Be aware that they are NOT above underhanded methods such as disinformation and slander.
