I think your guild names should be plural possessive because guilds by definition are more than one person.
Thus, Adventurers' Guild, Mages' Guild, etc. Or at least be consistent on usage, a few places were missing an apostrophe. Maybe in the rest of the game text too.

Ingot prices decrease!

EV_cavecrawlers=market.create_price_event("Cave Crawlers","Cave Crawlers found in several gem mines on eastern Issanis! They ate a good amount of precious gems, making them overall more expensive.",
Cave Crawlers
were found...
When you say "overall" do you mean "everywhere"? Either way, move this word to the end of the sentence.
EV_fertilizer=market.create_price_event("Unfertile Lands","Farmers all around Icesilia are worried about their fields. Some kind of curse reduced the fertility of the terrain. All fertilizer items price greatly increased!",
Infertile Lands
I would say "has reduced the fertility".
The price of all fertilizer items
has greatly increased!
EV_thieves=market.create_price_event("Grand Theft","A band of very skilled thieves has robbed the Adventurer's Guild, stealing a variety of items. All item prices of Adventurer's Guild increased!",
A band of very skilled thieves has robbed the Adventurer
s' Guild, stealing a variety of items. All item prices

EV_pirates=market.create_price_event("Pirates?","Rumors says one of the ships who has just arrived at the docks is from Shacklesplit. They could be trying to quickly resell some stolen goods. Not sure if it's true, but all tier1-3 item prices are lowered at the docks.",
Either "Rumors say" or "Rumor says"
I think you were labeling Tiers with a space now, right? So it'd be "Tier 1-3 item prices
have been lowered..."
EV_locusts=market.create_price_event("Locusts Swarm","A locusts swarm has destroyed many herbs and plants all around the region. Plants and herbs prices increases globally!",
Locust (no ending s) Swarm, both title and description.
Plant and
herb prices
increase globally!
EV_flood=market.create_price_event("Flooded Again","The herbalist shop got flooded again! All items price increases.",

item prices increase.
EV_taxes=market.create_price_event("Taxes, taxes","Our beloved King has raised the taxes for all shops to help fund a new Summer Palace along the coast of Reol Bay. Long live the King! All items are more expensive in Icesilia vendors.",
Nitpick: Everywhere else you've been capitalizing all words in the title. E.g. "Taxes, Taxes" unless it's a quoted reference to something.
"in Icesilia vendors" should be "on", "for", "at", or maybe "from" but I'm unsure which without more context. Is Icesilia the local town or a group of foreign merchants (I haven't been paying attention)? Are the prices for buying, selling, or both activities higher?
EV_deflation=market.create_price_event("Deflation","High unemployement and the ongoing wars with orcs and goblins has caused an economic deflation, the price of all items decreases.",
I'd replace the , with a period and make it two sentences.
EV_seafestival=market.create_price_event("Festival of the Sea","It is said that the town of Icesilia was founded on the 50th day of Arboris by some men coming from the sea, and the sea blessed the town itself with its endless resources. All guilds offer their potions and potions-related items greatly discounted.",
"some men coming from the sea" is grammatically correct but sounds a little silly since it makes those men sound totally unimportant ("ehh, don't worry about them, they're just some men!").

I'm not sure how to tweak this as I'm unfamiliar with the history and lore behind the town. Maybe just delete "some"?
potion-related (no s) items
at a great discount.
EV_abundancefestival=market.create_price_event("Festival of Abundance","Every year the 25th of Floreas the Festival of Abundance takes place. As tradition, all the food items are greatly discounted in the market, docks and herbalist shop.",
Every year
, on the 25th of Floreas
,
Per tradition,
all food items...
