A warm welcome to you and your story!
I love your concept of the immortal elf who can periodically come back, routinely changing to a different kind of elf. I like the fact that you pay elven homage to the manmer Bretonic race.

Chapter One. Three paragraphs that tease us right into your story and effectively tell us what we need to know at this point. We have many questions, but that is why we will return to learn more as your manmer reveals it.
Oh, let’s touch on just a few tiny things to consider in your editing.
Capitalization. You use the word ‘Journal’, then in the next sentence use ‘journal’. I would go with the uncapitalized version in both cases. Another way to look at this is to ask, why in the world would you capitalize journal unless you were talking about the title of a specific book like Riften’s Journal or Buffy’s Journal.
Tenses. In your last paragraph, you say he 'goes' by the name Valen Dreth. Two problems here. Valen is dead and your story is in the past tense. Both these factors suggest that he 'went' by the name Valen Dreth. In the next sentence, you use another present tense word, seems. This is less problematic because it can depend on your intent. Seems would be okay if your intent is to imply permanency – using seems in a past tense story implies that Valen did seem and would continue to seem a prisoner. It can be tricky to use and not recommended in this instance.
Long sentences. Short crisp sentences will generally trump long complicated ones. If you review your post, you will see a marked trend toward overly long sentences. Lots of commas are a good clue that your sentences are too long.
Word selection. ‘…journal was poorly written, barely unreadable.’ This doesn’t work and is somewhat analogous to a double negative. If it was barely (or otherwise) unreadable, our hero couldn’t read it. What you want is: ‘…journal was poorly written, barely readable.’ Or, if you prefer, you could say ‘…journal was poorly written, almost unreadable.’

Chapter Two. I was very surprised to see you posting a new update (albeit they are short). I was in the process of posting my comments on Chapter One when I just happened to check and realize you had just posted Chapter Two. Don’t do that.

If you want to post a longer update, say even up to 2000 words, do so, but don’t post updates more often than three times a week. Give people plenty of time to savor your posts and realize that most of us follow quite a few other stories. Don’t burn out your readers by either too much or too fast.
Okay, now Chapter Two itself. We learn much of our mage here. You presented everything in an interesting a logical manner. Clever use of the immigration papers to spill Riften’s essentials to us. Riften then indicates he seems interested in an Arcane education perhaps.
Let me just focus on one troublesome area here:
’I headed into the city, it was filled with bustling people, It truly has grown since I last seen it.
I walked into the office and was greeted by a young Imperial girl'1. The first sentence is a run on of too many clauses. Even you sort of realize that as you capitalized ‘It’ in the middle of the sentence. Simply rework this into two smooth sentences.
2. At the end of the first sentence, you want ‘saw’, not ‘seen’.
3. Since the second sentence starts a new line, I presume you intend for it to be a new paragraph? If so, add a line space between paragraphs. If it is your intent that it all be one paragraph, then don’t push the last sentence to start its own line.
4. Add a period to the end of the last sentence after ‘girl’.

Again, I’m so pleased that you are bringing Riften to us here at Chorrol. You are off to a wonderful and interesting start. I very much look forward to reading more - after you give everyone some time to enjoy what you have already posted.
