Overall, not enough story to judge. Sisterly rivalry is nice, but the cumbersome use of "hooded figure 1 and 2." made the beginning a little clunky. The idea of a war is pretty common, and a race for a powerful artefact is reasonable. However, the human seems wayyy too into that "infinite power" schtick. It's obvious that you plan to expand on it to something more like a way home for the person, but the way you had the human react made it seem he was in it for power/control instead of escape. Maybe try hinting at that intent through a slightly extended conversation with Celestia? Otherwise, the story seemed aight.

Below are some observations

Luna had pitied her sister, "Pah, I bet you shall be rejected in as soon as you finish your speech."

does not seem like Luna pities Celestia here.

a paper that was meant to be used to request warriors for the war. But she found none that had taken part to it, with scrapes and cuts to the paper, even a dagger at the middle of the paper.

using paper twice in a sentence makes it flow a little worse IMO. (just felt awkward to read).

Sol Lice

I think you meant Solstice, or am I tripping here?

malicious tyrannical evil King

I'm pretty sure you're supposed to use commas in lists like this, if not, then maybe try toning down the redundant descriptors?

Thanks so much for the feedback! I'm going to work on them right now, and as for your questions I meant to make the human have more adaptablity and strength. I want to state that the idea is he's human, he's strong but not strong enough to lift a giant boulder. I'll try to extend that line of thought next chapter, hope to receive more feedback from you as I go along.

TLDR; Human is just that, human. Not meant to be super strong or powered with magic and doesn't want power.

well yea, that's not what I take issue with. No superhuman extreme shit has been done. What I mean is that the human comes off as another power-hungry villain in this chapter because its.

"Please, lives are at stake."

"I don't care."

"...uhhh, how bout your friends and family?"

"ded."

"... How bout an artefact with infinite pow-"

"I'M IN THIS BICH."

which makes me think either hyper greedy mercenary or power-hungry villain. Especially because you just left a scene with a number of those kinds of characters. Which isn't bad in itself, but the description makes it seem like you want this human to be a hero, with this chapter was being meant to set him up as a reluctant one.

I'll make it clear next chapter but... Basically he's an alien and separates himself from ponies, he's more of an anti-hero if anything, but the idea isn't 'he is a hero' it's more like he becomes the hero.

Author's Note:

Slightly inspired by a story where Faust is trying to keep baby Celestia safe? I don't recall the name and I stopped reading it a long time ago so if anyone or anypony could help me find it again do credit it, I would greatly appreciate it

"The story's name is Preunification anon by Spooples"

No problem happy to help

Is there a voting system that allows to vote what you should do next? If so, I join someone other than Celestia and her ponies. Just saying; this feels more like Total War Warhammer 3 factions.

Good so far despite the guy not turned into a pony, Keep it up.

More pls and thank u
