In Book 5: Kaiser Wilhelm Appears! Svyatozar's diary and the story of his past! Will Iskren obey the order of the Priestess of the Moon? Avril and Zima will part again or not?

Excerpts from the Book 5:
... Wilhelm sent his loyal agents to the Kingdom of Daro, to the city of Antaea. The agents were good at convincing people, therefore they quickly got into the trust of local sectarians. And they gave one of the 'Projectors of Body' to the followers of Asura.
"The goddess Asura herself told us in a dream how to create this artifact. But she also set a condition: when we finish the artifact, we will forget how to create it," one of the agents told the sectarians. "This is not just a projector, with its help we can get into direct contact with one of the highest demons of the great goddess Asura, the Dark General."
Among the followers of the dark goddess, there were legends that Asura had her own personal dark army. And it is headed by a certain Dark General.
When the Kaiser's agents presented the 'Projector of Body' as the artifact of the goddess, the cultists became agitated. Of course, the agents were able to convince cultists that they were on the side of the followers of the dark cult, but still the sectarians were a little wary of the outsiders.
But when they turned on the 'Projector of Body' and a large light screen appeared in the air, the sectarians froze in amazement, trying to comprehend what they saw. And when they realized, they prostrated themselves, reverently exclaiming:
"Dark General! Great Dark General of our mighty goddess Asura! We see you through a portal to another world!"
Indeed, from the other side of the screen, a man in a frightening mask, with long hair and in dark armor was looking at them. He sat on a dark throne in a dark room. On the table in front of him were burning candles and crystals of bizarre shapes. Behind him, to the left and to the right of him, were two more men, also wearing masks and dark armor...

...Iskren and earlier it sickened. But the task to 'remove' Vera and Jan seemed to be the 'last straw'. And the less time remained, the more he was tormented.
"I have no choice..." Pilot lamented mentally. "If I don't do it, what will happen then? How will the Priestess of the Moon punish me for disobedience? Will she only punish me, or will she harm my family? I have to do this today... I have to pick a moment and plant the spell scroll in MeG of Jan and Vera. Tomorrow I may not have an opportunity..."

From the diary of Berislav, who later took the name of Svyatozar
04/01/715 post-Renaissance
How do people start writing diaries? It is generally believed that girls do this, but sometimes I also need to organize my feelings and thoughts. Well, so be it.
Today is 04/01/715, the year post-Renaissance. And I, Berislav (I have no surname, like the commoner), begin to write my diary.
I was born on December 22, on the day of the winter solstice, in the year 700 post-Renaissance, in the Kingdom of Wend, in the vicinity of the city of Agunika, which is not far from the capital of our country, Mokoshin.
Wend is renowned for its ancient history and rich cultural heritage. We, like all countries located on the Central Continent, do not have certain cults. We simply worship the abstract forces of nature. Shamans, priests and priestesses of the forces of nature are highly respected in society.
