History Fanfic / IncompatibleSystem

* FalseFlagOperation: Kind of but not for the usual reasons. [[spoiler:Geth decide to hunt down Batarian pirates to protect Creators, while making sure that the Council races cannot identify them as Geth. At the same time, they want to use weapons that were inspired by Humanx gamma laser with hopes of drawing their attention and making contact.]]

* HiddenDepths: Lord Alamo is initially described as "A ten gallon hat with a five gallon man trying to hide in it" and is usually very loud and blustery. However, once aliens are confirmed to exist, he makes several impressive insights regarding them.

* HumansAreCthulhu: When the Citadel races discover someone had been stealing Mass Relays, they certainly get the feeling the ones responsible must be some EldritchAbomination.
** [[spoiler: The Geth meanwhile immediately [[DidYouJustFlipOffCthulhu prepare to poke said abomination]].]]

** The disappearance of Relays is this from the Council perspective. Not only they have no idea ''who'' did this or ''when'', or ''how'', or ''why''. They also have no sign that those Relays had '''ever''' been there besides some documents that say so. All of this means that there might have been other Relays that disappeared and they will never know now because they weren't documented.

** The crew of Rylix, upon realizing their drive is out.

** The Citadel leaders, once they learned someone had been removing Mass Relays, cutting off a large chunk of space.

* OneWorldOrder: Humanity is headed there, although a few states are still staying out.
** Though it seems to be showing some cracks / signs of being a forced development. The [[ExactlyWhatItSaysOnTheTin "Empire of Texas"]] for example, pushes for independent colonization of space. The current ruling entity of Earth is in a position to outright block them, and presumably others, from doing so AND is denying them the technology they would need to head out on their own.

* TakeMeToYourLeader: The ship sent to make FirstContact with the Thranx is called ''We Come In Peace''. Not that the Thranx are likely to get the reference (although, with their similar thinking, it's not impossible they have an analogue of the expression).

* WorldWarIII: In 2034, almost two dozen cities were leveled by some terrorists in a massive attack of unclear purpose. A full scale war was narrowly averted, but it's still half a billion casualties. And then a billion more indirect ones.

** Considering how destructive is dstabilized eezo and how ''easy'' it is to set off the reaction, the Humanity invests a lot of resources into technology that can detect even microscopic quantities from light years away and heavily regulates exploration of unknown systems.

''Incompatible System'' is a ''Franchise/MassEffect'' AU fanfic by mp3.1415player, with elements of ''Literature/HumanxCommonwealth'' added in. Currently, it's available on [[https://forums.sufficientvelocity.com/threads/incompatible-system.57005/ Sufficient Velocity]], [[https://forums.spacebattles.com/threads/incompatible-system-mass-effect-au.777778/ SpaceBatttles]] and [[https://www.fanfiction.net/s/13366586/1/Incompatible-System Fanfiction.Net]].

* ConfirmationBias: InUniverse. Thanks to their first and ''very'' destructive meeting with Planium[=/=]Eezo, Humanity spends a couple decades outright refusing to seriously consider that Mass Relays could possibly be anything other than enormous weapon arrays of some kind. It's not until they crack the encryptions on a Relays' software that they learn otherwise.

* TheComicallySerious: The Geth have no sense of humor but manage to be outright hilarious regardless. When trying to contact humanity, they get the idea to attack Batarian pirates as that is the only definitive interaction humans have had with the Citadel races. When the idea of "depleting Batarian pirate supply" comes up, the Geth note that the Batarians "exhibit insufficient cognitive ability" and that it's unlikely they'll run out any time soon.

** Tevos's thoughts imply that some Citadel worlds might have been experimenting with WIMP technology, given her thoughts about how said planets mysteriously exploded.

* {{Foreshadowing}}: Not long after first contact between Humanity and Thranx, it's mentioned that it would be theoretically possible to move a planet with their combined technology. In chapter 11, an interlude set roughly thirty years in the future has Tevos learning that [[spoiler:Rannoch is missing]].

** A Turian patrol discovers the Migrant Fleet nearly thirty years after every Quarian seemingly vanished from the galaxy. The entire fleet is abandoned and unpowered, but the ships show no signs of a struggle or battle despite clear evidence that they were abandoned in a hurry. The investigating Turians spend their several hour long search jumping at shadows and ready to shoot at the slightest sign of movement.

** Considering how destructive is destabilized eezo and how ''easy'' it is to set off the reaction, the Humanity invests a lot of resources into technology that can detect even microscopic quantities from light years away and heavily regulates exploration of unknown systems.

* {{Expy}}: Lyzenzuzex is basically an alien version of [[Series/BigBangTheory Sheldon Cooper]], down to quoting some of his lines.

* EarthShatteringKaboom: The eventual solution to dealing with the Charon Mass Relay is to drag the entire moon out of the solar system and blow it up. According to later chapters, the resulting black hole consumed approximately half the moon's mass.

* HandSignals: Not quite to the level of SignedLanguage, but Low Thranx involves a lot of gestures involving four arms and a pair of antennae to convey certain meanings.

* ConfirmationBias: InUniverse. Thanks to their first and ''very'' destructive meeting with Planium[=/=]Eezo, Humanity outright refuses to even consider, for a large part of the story so far, that Mass Relays could possibly be anything other than enormous weapon arrays of some kind. [[spoiler:It's not until they crack the encryptions on Relays' software that they learn otherwise.]]
