The book series I'm working on can basically be summed up as a science-fantasy series that starts out leaning much more on the fantasy end of the spectrum but moves more and more towards the sci-fi end of the spectrum as it progresses until it looks like a cross between the Legend of Korra and Star Wars by the end.
The way this happens is that the setting is essentially a brutal, 19-year-long war between the galaxy's biggest powers that industrializes the wider galaxy in what is practically the blink of an eye.
Setting and plot details
At the outbreak of war, the three main powers can basically be summed up as follows:
Based on the culture of Victorian-era London
Ecumenopolis similar to Coruscant from Star Wars
Technology so advanced it's basically indistinguishable from magic
Had its industrial revolution about 200 years ago and has been led by a royal family that bullied weaker planets for land and resources while greedily hoarding its own advancements ever since (however, a new king named Michael who is a supporting protagonist has ousted the old dynasty and wants to both democratize the planet and end and atone for the oppressive system of colonialism for which his forefathers are responsible. However, this is complicated by the fact that many of these colonies will be needed to win this galactic equivalent of WWII.)
One main planet but has colonized several previously uninhabited worlds around it for use as farming colonies to feed itself and has bullied resources out of and taken land from worlds that are inhabited, to the detriment of those who live there.
By far the most populous of the three main powers, being home to almost half the entire galaxy's population
Based mostly on Greco-Roman culture, but three of the outlying provinces are descended from various waves of settlers from elsewhere and are based mostly on Zulu, Mongolian, and Maori cultures respectively.
The military is based on the late Roman imperial system (but with Kommnenian-era Byzantine technology and weaponry), and the government is essentially the Roman Republic with a non-term-limited US President called the "Dominus" in lieu of Consuls.
Least populous of the three main powers.
Aurea's current Dominus (president) is our main protagonist, who is a close friend of King Michael of Ishga, and will spend the first few books both defending Aurea from Tate's minions and implementing an absolute ton of reforms to rapidly modernize the planet.
Aurea is a single planet.
Like all preindustrial worlds, Aurea conducts space travel with Startreaders, which I outlined in the context for a previous question.
Those three outlying provinces I mentioned are composed of people groups completely separate from most Aureans, were conquered by the Aurean Government a few centuries back, and have a complicated relationship with their identity as Aureans, as well as with the Aurean Government.
Most of its population is composed of dozens of tribes based on various Native American and Inuit cultures that live in rural areas. However, its government and military are mostly run by the detribalized urban population of mixed tribal heritage. This detribalized population only exists, however, because of a policy implemented a few decades back by Tate, which kicks rebellious tribes off their lands, forcibly disbands them, and scatters their people into various cities spread out across the planet.
Led by Tate, a rogue mutant of Ishga heritage whose mutation gives him talent with magic that rivals the Gods' powers. Tate is the main antagonist of the series and bases his worldview on the Ishgas' previous oppression of the galaxy. He sees the galaxy as so thoroughly ruined by Ishga colonialism that he wants to either conquer it all and rule it himself to fix the damage or find and use a combination of long-lost ancient artifacts to summon the 3 primordial beings of the galaxy and have them create a new galaxy in his own image. His plan switches back and forth between the two depending on how well he is doing in the war (when he is winning and controls most of the galaxy, he is fine with the first plan, the second is his backup in case he starts losing). Tate rules Caput Tatiium as an absolute monarch.
Second most populous of the three main powers.
Has spent the past three decades or so industrializing and modernizing its military with stolen Ishga technology acquired through Tate's allies in the galaxy's criminal underworld. However, most of these benefits have only reached the cities, and there is a massive wealth and technology gap between the cities and rural tribes.
Uses its location on the far western edge of the galaxy (which has a reputation for being a barely inhabited backwater) to hide its massive industrialization projects and expansion through UNISYN.
Originally called Navayu before Tate's rule
Various UNISYN Colonies
Before Tate's rise to power on Caput Tatiium, the vast majority of habitable planets in the galaxy were uninhabited. Seeing the golden opportunity, Tate, along with several prominent members of the galaxy's criminal underworld set up a massive pyramid scheme disguised as a legitimate company in which UNISYN sold people land on these worlds, and these people were rewarded for getting friends of theirs to buy in and get friends to join as well, and so on and so forth. The profits from this are basically what keep Caput Tatiium financially afloat.
The majority of the war will be fought here.
UNISYN worlds occupy the vast majority of the galaxy's area.
The vast majority of these worlds side with Tate and their inhabitants form the bulk of his military.
UNISYN Colonists are comrpised of all of the peoples of the galaxy, but those of Aurean, Caput Tatiian, and Ishga descent form a narrow majority of the population of these worlds.
Combined, the UNISYN colonies are second in population only to Ishga and will grow rapidly even as the war goes on.
Rest of the Galaxy
Composed of 10 Worlds: Planet Squid, Aztlan, Awal, Arturia, Ryu 97, Ryu 108, Atlantea, Bharatam, Vigam, and Rinascita
All are generally at early Renaissance levels of technological, military, and societal development.
Vigam, Aztlan, and Atlantea all have parts of their land under Ishga rule, Arturia has a history of oppressive Ishga rule in the past (although the current ruler has put this behind him and is a close friend of King Michael), and the rest all have some sort of unequal treaties with Ishga (kind of like the ones set up by European powers with China after the Opium Wars).
Combined, these worlds are more populous than Aurea but less so than the UNISYN worlds. Many battles of the war will be fought here as well, as they are the cultural, historical, and magical heart of the galaxy and are home to most of the artifacts Tate needs for his ritual.
These worlds will tepidly side with Ishga and Aurea at first, but many of their citizens have Tatian sympathies and all of these worlds change hands at least once during the war. Aztlan is the exception as Tate simply takes an artifact he needs, commits an almost total genocide on Aztlan's populace for reasons not relevant to this question, then leaves.
The vast majority of both supporting protagonists and supporting antagonists are from these worlds.
Now that we have that massive info dump out of the way, here is my question:
Does having the reforming but still colonialist world of Ishga and the sort-of-colonialist world of Aurea portrayed as mostly "the good guys", while the (on paper) anti-colonialist (but incredibly hypocritical) world of Caput Tatiium portrayed as mostly "the bad guys" make it look like I am promoting colonialism rather than being anti-colonialist?
I already asked this on Worldbuilding SE and they closed it and told me it belonged here, so here it is.
