I am here by request through Discord. Reviewing only Part 1:
Overall, I think this has potential to be a really good Part 1 to a larger series, but there are some things you should address first:
So, I must say that I feel a little lost. I like the concept, but you are throwing in a lot of place-names but not really mentioning their significance. As MuseHill mentioned earlier, establishing things like location and direction (east, west, north, south, are they close to Berlin, far from Russia, etc.) is really important so try to work on that more. Additionally, describe certain things a little more:
The Library
What does this look like? Why is it being targeted? Where is it in relation to the Harpian Zone?
Madrid native ghetto
Where is this? What does it look like?
to rush to the Harpian zone
Where is this? What does it look like?
get in the car
Wouldn't the roads be blocked? Where is the Harpian Zone in relation to the rest of the city, and why can't the mob just break in/attack them as they leave?
Answer the above and more; if you feel like more descriptions would hurt your story, then don't add them or don't add too much. As of right now, though, I feel really lost, and I don't feel like the scenario is unique or memorable without a solid sense of place.
Another big issue is the fact that there isn't much characterization of Zihar, Oru, and their parents, and there aren't many details about his life. What is he leaving behind exactly? How does he feel about the conflict at hand/what does he know? Has he overheard anything from his parents? What do his parents feel?
There are many perspectives you can write about—don't be afraid to explore the different perspectives of people in the story, like Zihar's friends, the people rioting, the security guards, or even Colvodor the Third! That's what makes alternate human history stories worthwhile.
The tone of the Imperial Order should be more formal and have proper punctuation, and the verb tenses need to be consistent in the newsletter at the start.
There are minor SPaG errors throughout, so please address that before posting. If you'd like me to point out each error, let me know. Keep up the work. Develop the plot, characters, and setting more so I can get a better feel for what this story is in your head.
