Hi, Author here. Just wanted to clear up any misunderstandings, as I feel that I didn't explain the workings of his wishes enough, so it may cause confusion.
First, for the powers of the shadow monarch, Nathaniel gets the abilities themselves, and not the full system. He also, has to fill his shadow soldiers himself, and wont have access to the soldiers from Solo Leveling, though I may make it so he can sacrifice a number of regular soldiers to create the more powerful soldiers from Solo Leveling, for example Beru, but only if you guys, the readers, want that, as i want to make the fic as enjoyable for you.
Secondly, for the Nasuverse/Fateverse servants, I wanted the MC to have 7 servants, one for each class, However, as I stated before, I want to make this enjoyable for all of the readers, but didn't want to give Nathaniel an unlimited amount of servants. I decided that the MC will have 14 servants, 2 of each class, and when it's time to summon a servant, i'll leave a poll, here on WebNovel with the options. After I post a poll, I will stop posting for a week to let the people vote and then post the next chapter with the option with the most votes.
Lastly, the matter of his sorting. I tought it would be rather obvious by his name, but i'm leaning towards Hufflepuff, mainly because they are severly under estimated, so not many would think a rising Dark Lord would reside there. I do know not many people enjoy stories with Hufflepuff protagonists, so if you believe he should be in another house, comment what house and the reason and i'll look through them and see if you guys have thoughts i might have missed.
The first servant will be summoned next chapter, so here's the first poll. (Please leave a comment on any Servants I missed that you would Like to be in the Fic.)
Lancer Class Servant.
1) Altria Pendragon (Lancer)
2) Cu Chulainn
3) Medusa (Lancer)
4) Scathach
5) Leonidas I
