So where do I buy the stylus pen that came with my Boox Air Note 5C? If can't buy it, what would be a good replacement for it?

Instead of just one Isekaied person, I plan on having more than one or few Isekaied people being dropped into my Dark Fantasy World with merely the clothes they wore and whatever they had on hand.

What is the best population number/s to restart Mankind and Civilizational Progress in a Dark, Fantasy World? Big enough to not only restart Civilization but also restart its progression into Modernity and Beyond in the near future in a Dark, Fantasy World? Yet, small enough to motivate the people who were Isekaied into the Dark, Fantasy World to band together to not only survive but thrive as a nation?

In Fantasy/Dark Fantasy, most people would draw their attention to Royalty, the Nobility, the knights, the Mages and the Merchants in Medieval Society/Societies for someone who is important enough to have an important impact in the plot of the story/stories.

Too often they underestimate, the local town's/city's priest who presides in the church or Cathedral. For it is the Institutional power behind the Priest that gives him great power over Medieval Society: The Roman Catholic Church

I will not go over Catechism Doctrine in the Roman Catholic Church during the Medieval period, but I will go over it's impacts during the Medieval period.

Impacts:

1. It was the last institution born and present during the Roman Imperial Era. It had a lot of literary works born during Ancient Era that they not only translated to Latin but maintained them in great condition. Without which there could be no Renaissance nor Industrial Revolution which would lead to our Modern times.

2. The Roman Catholic Church trained many not only priests but theologians whose work would greatly impact Human Civilization like Philosophy and the different Sciences. For example, the Gregorian Calendar is considered the most popular form of Calendar so much so that it is standardly adopted all around the world even among countries who have a minority of Christian population.

3. With Barbarian hordes marauding all over the Roman Empire, many of their chiefs and chieftains could barely read nor write, so they often employed the Clergy to not only write but also read to them their laws.

4. Before the Medieval Era, Kings and Emperors often crowned themselves as Demigods who are merely bound to the will of Gods who often reward strength above all else granting them near unlimited powers to do what they please. During the Medieval Era, the Roman Catholic Church pioneered the "Divine Right" of Kings to follow. In which their word has a legitimizing effect on the European kings on their rule in which they agree follow Morals championed by the Church. So much so was the legitimizing power of the Roman Catholic Church that the organization's will dictated the fall and rise of Empires during the Medieval Era.

Yet, the role of Religion during Medieval fantasy/Dark Fantasy is often ignored or downplayed in many stories. With the Clergy often being downplayed as petty tyrants

So I ask:

What do you need to do to write a Fictional Religion that not only has a huge impact on different societies like the Roman Catholic Church in a Fantasy/Dark Fantasy setting? What is the best way or what are the best ways to make it interesting in your story and Worldbuilding project?
