In case anyone is confused about my post, it's about the 0-2 defeat the Tollscythes suffered at the hands of the Brinzespears and in which a trade agreement with the Horselords was somehow involved.

Please forgive me for low quality writing, this is kinda new to me ;-;

Au contrare, some excellent poetry. Very glad you came by. A small few technical formatting issues though;

watched and lo!, a great Host of Horselords (P1)
Grammar and style guide dictate no exclamation here, although I see the poetic merits.

O, how chilling was their cry for blood (P5)
Correct that to 'Oh' if you would, for the sake of common translation (I again see why it is tempting to put this in but again common style).

Quote Attribution
Instead of having a title in the quote, please just append it to the italicized title at the beginning and add Trollscythe's name to the beginning in bold. Also, remove the space between title and quote.

Miscellaneous
You mentioned the line of Skullgate which doesn't exist (you likely meant Tollscythe), I saw you misspelled travelers somewhere, you capitalized host in the first paragraph. I think that was all.

Since this is your first time with the style guide, I went ahead and made these into one copypasta since they were minor.

[i]Years and Customs of the Tollscythes: The Massacre at Deythurn[/i]
[b]Chief Argel Sullgate Tollscythe[/b]
[quote=Brother Sturgeon of Naucalia, Servant of the Morcelian Order, Witness of the Messenger]
So it then became apparent to Chief Argel Skullgate, lord of the Deadman Mountains and bear of the southeast, that a novel change in the affairs of men was present. One sunny day, all of the clan of Tollscythe watched and lo, a great host of Horselords, awash in oaken shields and painted with the spirits of their fallen, sojourned into the camps of the great chiefs. Their leader, who bore upon him a great brazen hauberk and a large battle-axe, dismounted his steed and entreatied that the lord of the Deadlands come forward. The lord came, gilded with his tall feathered helm and great tall spear, and asked their business.
The Horselord bore his tidings. His chief the great Ulden Strongsaddle, bringer of the wrath of horse-hooves and the messenger of thunder, wished to parlay their tolls. As was the usual custom of the Tollscythes when dealing with other powers, they compensated for their abject lack of territory with charging unwary travelers exorbitant fees, lest they be assailed by beasts of the mountains or braves of their chief. My lord the Chief Argel did follow this ancient custom, and he bid the Horselord farewell, sending with him tidings of a renewed accord. 
But the Horselord would not take his leave. He again bargained for lower tolls, less braves roaming the mountains, a safer passage. Thus was the parlay prolonged. After much argument, my lord the Chief Argel did agree to discuss more terms with the Chief of the Horselords himself. The great son of Strongsaddle agreed, but on the only terms that his party for parlay would come unarmed to their land. My lord the Chief Argel unwittingly agreed, unaware that his grave error would bring ruin to the name of Skullgate.

And so the two Hosts journeyed in the the Deythurn pass, the passage of the dead, where the Great Thunder smote those unwilling of the afterlife. It was then that the Bronzespears attacked.
Oh, how chilling was their cry for blood as they came pouring over the pass! How swift their arrows, and how cold their steel against flesh! At least two hundred in number overwhelmed our numbers of sixty and the forty of the Horselords. The pass was bathed in blood, the very earth stained with the innocent blood of young warriors! How dishonorable! How unfortunate! May the wrath of the Ascended bring judgement on he, lord Gultuk, sparer of no man's life, scum of the earth! My lord Argel was smitten in his right shoulder by an arrow, and was borne away from the inferno by two of his great braves. Of the Horselords I do not know. We lost fifty of our own.

[...]

Thus was one of the most abhorrent atrocities that ever befell the line of Tollscythe. My lord Argel was not to speak to another man for many months, and he was to be more careful in his dealings if the need should arise.[/quote]

If you could either make changes yourself or copy that in when you have a chance, that'd be great.

Also, I highly encourage you to come on the discord for more fluid conversation, announcements, and socialization.

In total though, welcome! A stunning entrance if I might remark.
