To those watching at home, Piltover in the pre-arcane lore always had an under-the-table hostile position toward Noxus from the get-go. This wasn't because of some specific event (because relying on specific events for state-v-state antagonism is over simplistic) but because of actual logic. Piltover wasn't hit with the stupid bat like they were in Arcane. Noxus is a rapacious, murderous empire that is extremely open and explicit about their desires to conquer everything (most empires are usually not so obvious). Noxus has already conquered much of the territory surrounding Piltover, and Piltover itself is an incredibly important strategic location that is the only link between the Eastern and Western oceans. Even ignoring Hextech and general wealth they've accrued, Piltover would always know that they are very close to being on the chopping block.

So what does Piltover do? It actually had half a brain unlike in Arcane and had sought to bilk Noxus for everything it can and placate them where possible while distracting Noxus with irrelevant issues using economic influence, espionage, and misdirection. It knew that it cannot fight an existentialist total war with them (although Pilt's navy was considered a fearsome one), so it sought to keep itself out of Noxus' gaze while getting it entangled in irrelevant theaters of war and internal rebellions/court intrigue that ensure that it can never bring a strong, collective response against Piltover.

This takes many forms and some are more morally dubious than others. The most morally dubious one is that Piltover does facilitate some Noxian expansionism. Sea passage through the Sun Gates has allowed Noxus to expand westward at a significantly faster pace than before (Swain's conquests in Shurima would not have been possible), although Piltover does charge exorbitant fees for their military passages to the point of bankrupting the previous Noxian regime.

At the same time on the more incidentally morally upstanding end Piltover actively provides and sells arms and material to anti-Noxian resistance movements in Shurima (like the Suns of Bel'Zhun) and to independent powers like Stonewall and various Ionian factions resisting Noxian incursions.

Piltover had interesting things going on in the wider world and the institutions that were a wealth of storytelling potential that add good conflicts and depth to the region. Things like the Inteligencers of the major Piltovan Clans like Camille offered interesting subterfuge and and espionage activities in games of tit-for-tat against Noxian Warmasons and Black Rose incursions. But we can't have those because for Arcane they needed Piltover to be bunch of dumb-as-rocks morons. All to make Noxus look "cooler".

It's also not even an unheard of situation that a smaller power can deter a significantly larger one by being a porcupine. People often fall into imperialist propaganda and assume that an empire that desires to destroy something can *always* do so. Athens was a hornets nest that the Persians for centuries preferred to never outright provoke it because the cost of doing so was so prohibitive. Theoretically Athens could be crushed by Persian size, but locally Athens had too heavy a naval presence in the Eastern Mediterranean for them to want to bother and so they had to find proxies and indirect means to weaken them (this ended up being Sparta). Where Athens and Piltover differ is that the former was desiring to be an imperial power while the latter is not so more diffuse methods of deterrence are politically palatable and available to Piltover.

There's much more avenues for storytelling by leaning into conflict between Piltover and Noxus than in making them buddy-buddies.

Ironically, pre-Arcane it had been Zaunites who have provided the most explicit material support for Noxian imperialism in the form of chemtech expertise, weapons sales, and direct assistance in several genocides during the Ionian invasion (don't worry though, Rito always ensures that there's a "good" Noxian to make a sad face at it though so we know they don't approve...). This was an interesting situation as we can understand and even empathize with the reasons why they'd do this. Gotta get that cheddar as one might say when the avenues for opportunity in Zaun itself are so limited. But nuance like the sympathetic Zaunites doing bad things to people because they benefit from the suffering of people that don't affect them is apparently too much for the writers (or the fandom, probably) to handle.

if you had to live in a fictional world from one of ur fandoms for a day, which one would it be and why?

have a nice morning/day/evening :3

Hmm...

If I pick Life is Strange then nothing changes...

If i pick Resident Evil I'm totally fucked...

Different regions have unique qualities to them. These qualities should be genuinely engaged with by narratives, not ignored. Qualities include some cultural, some physical, etc. and all alter how Leblanc/the Rose/Noxus operate and what intel they can even get:

Demacia: LB like most Noxians find Demacia a painfully annoying thorn in their side. Petricite walls and shadowy interventions of the veiled lady make most magically assisted infiltrations next to impossible. No clones, no teleportation, no swapping bodies, no magic assisted interrogations or information sharing, etc. Any and all espionage has to be done the old fashioned way. The Rose/Noxus has to play "fairly" or not at all. "Grit and spit" methods like trying to recruit local agents (Demacians can spot a foreign accent a mile away despite efforts to hide it), bribery, extortion, etc. However, this leaves Leblanc's plans dependent on mortals who are flighty at best of times.

Targon: LB can send spies and clones to Targon but doesn’t derive much value from them directly. Understanding Targonian celestial divinations is difficult enough at the best of times, and prophecy more often than not will bite you in the arse no matter what you do, but the mountain does produce a treasure trove of prophecies that she can use for misdirection elsewhere in the world. Isolated geography and the constant eye of celestial empowered inquisitors make intel missions high risk dubious reward so LB sticks to gathering divinations for use in other regions.

Piltover: Clan Inteligencers, particularly those empowered by hextech, are an equal match for Rose agents and other Noxian spies. The trade connections the clans also hold make them capable of similar global reach as the Rose and equal in blackmail and bribery potential. Tit-for-tat escalation is a high risk as agent actions in Piltover can quickly result in counter espionage actions by Inteligencers across the globe where the Rose might least expect. Infiltration of Piltover is easy due to its high level of societal openness, but care has to be done in order to avoid a cascade of reprisals across the Empire.

Ionia: Raum, a historically valuable asset, proved quite limited during and prior to the first invasion and was not much use in gaining intel in Ionia. Kinkou wards, the land's spirits, and peculiarities of Ionian burial practices made it difficult for Raum to consume secrets from Ionian dead. The demon was only easily able to consume the secrets of stagnant souls of Noxian dead that were categorically rejected from an afterlife by the spirit of Ionia. So his role was repurposed for gathering secrets on Noxians who fell in battle rather than on Ionia itself. Other demonic vassals in the Rose's employ were more useful to the war but ended up destroying most anything of value in the process.

Freljord: Lissandra and LB have long had a détente of sorts between them. Frostguard are near impossible to infiltrate due to their iceborn preponderance and cultish socialization, and Liss is limited to collecting dreams of Noxians she's able to seduce from afar, not break into Noxus itself. Harsh terrain, Freljordian culture emphasizing familial bonds, and territorial nature of the tribes make Rose infiltration extremely difficult. Secrets of Freljordian resiliency remain just out of touch.

Ixtal: A man after her own heart, Skarner's eyes are everywhere with his vibration-based panopticon which makes direct infiltration a no-go. Able to sense even the slight change in someone's gait after being replaced by a clone, many Leblancs and agents die quickly or have to avoid drawing any attention to themselves thus making their effectiveness severely degraded. Ixaocan isolationism and rigid caste structure based entirely on elemental magic similarly makes high value infiltrations unlikely simply due to an inability to blend in. Ixtal still has value, however, as the traps woven by the Ixaocan arcologies and the general Ixtali jungles are a bounty of for repurposing. Poisons, plagues, and new monstrous creations from the local fauna can be collected (at great risk, often resulting in death of agent).
