Read Chapter 6. I think you kinda cleared up Olsen's sickness a little too fast, but you managed to foreshadow future events and weaken him for the impending confrontation with his brother at the same time, adding to the tension.
“Be weary Olsen, for this beast will devour you if you’re not, just like he did to your ancestors” he said seriously and the image of the man faded as Olsen realised he was falling from Caballo and his consciousness faded with the impact of his head with the ground.
Olsen slowly came to, his hearing was distant and impaired from his blow to the head as well as his vision remained spotty and dark.
You're trying to cram too much into this sentence. I'd break up like this:
"Olsen slowly came to. His hearing was distant and impaired from the blow to his head,
and his vision remained dark and spotty."
Note the use of "and." When you combine two complete sentences, you need a conjunction as well as a comma that helps to convey the relationship between them. Alternatively, you could use a semi-colon instead of the comma+conjunction.
You said your grammar could use some work. I don't know how much work, and if I've presumed too much, go right ahead and give me a slap on the wrist. I'm not sure how much you care about grammar, but if you can get your knowledge of it up to snuff, you'll win the adoration of grammar nazis everywhere.
Cerice smiled as she looked at his bloody face from where the blood had gushed out at inhuman rates, his nostrils and upper lip were crimson-dyed from his blood running down them
Blood, blood, blood. There's definitely a better way to re-word this description/trim it down to avoid saying "blood" so many times.
"Cerice managed a smile despite the ghastly state of Olsen's face. It was stained crimson from so much blood; it looked as if a five-year-old had covered it with face paint."
I cut out the info about the blood having run out of his nostrils and mouth because we were just told that several paragraphs ago.
Cerice looked over to Aria who stood with bent knees by Olsen’s side with an equally worried expression as Cerice
Aria shook at the sight of Olsen, she had never seen him so weak before, except for when he witness the death of his parents it felt almost unnatural for her to see Olsen in the state he was in.
Replace the commas with periods. Witness needs to be in the past tense. Add a comma after "parents"
You say that it's unnatural for Aria to
see Olsen in this state, but I think what you mean to say is that it's unnatural for Olsen to be like this. Not a terribly big difference, but it is a difference.
Cerice demanded and her men looked unsure “What is it?
Missing the period after unsure.
“My Lady, Magika’s only exist in a 50:1 ratio in the lands of Despra, they are a rare commodity and to find an expert Magika is almost impossible” Davies explained.
I believe your ratio is backwards.
“Aria, you shall ride Caballo until Olsen is fit enough, we need someone to just watch after it”
The part could just have another rider lead him along. I'm no horse expert, but they aren't stupid, especially a horse like Caballo, which is undoubtedly trained.
It is not the first time that blood had escaped you since we have travelled together but neither have they ever been so powerful while being expelled from your body”
Maybe it's just me, but those two phrases sound awkward.
Cerice began to start bargaining with Olsen about him waking him
Typo?
I do not know much about medicine but I believe you are not meant to offer wine to someone in poor health”
Actually, wine isn't a bad choice.
“They said you alone may enter with me and Aria because of your standing, while the men must fill out some extensive paperwork”
Isn't Aria the princess? Can't she just use her position to wave everyone through?
but the fact he spoke at all was an amazing and positive feat for him to accomplish given his state.
Bit of a stretch there. Initial attack aside, Olsen's symptoms as described seem in line with what you'd expect from a nasty but not life threatening sickness.
A man in a dark black cloak that covered his entire body with tattered ends stood in the middle of the street, blocking their path. He had black metal greaves on and boots with black metal gauntlets as well. He had his cowl pulled over his head so it cast a shadow over his face and obscured his features.
Not a fan of Ofre's physical appearance. Maybe it'll grow on me later if there's some reasoning placed behind why he looks the way he does, but for now, it just sounds like that of a stereotypical villain.
