Terraria: Cthulhu AU

Updated explanation

ok so i had to make some mini-changes to the au, and the other explanation if pretty old so, you know

anyways. explanation

also there's no capital letters because i have auto capitalisation off and i cannot be bothered to turn it on

***

moon lord and cthulhu are different beings.

moon lord is from a banished dimension that lunatic cultist accidentally opens access to during the timeline of the player's playthrough.

the dimension only opens once all the celestial pillars have been defeated, and all the pillars only appear if lunatic cultist is dead because... idk they do in the actual game so just stick with it

anyways, more about cthulhu.

cthulhu has a close connection to four bosses:
lunatic cultist, literally cthulhu's helper
empress of light, he helped her create the hallow
plantera, it's more of one-sided since plantera doesn't remember cthulhu but he helped her create the jungle
and golem because... the jungle temple idfk

cthulhu's body parts are of bosses, i mean
not all of them, like his hands, idfk what those are
hands of cthulhu new boss??/????/

anyways. those bosses are:
eye of cthulhu
brain of cthulhu
skeletron

eater of worlds also helps but isn't exactly a body part. it kinda had to help since destroyer is a thing and i refuse to leave destroyer out because i fucking love that thing

waaaaaaay before the player starts a new game, cthulhu makes a deal with wall of flesh. however, wof is a little shit and "betrayed" cthulhu by not doing their deal

idk what the deal is btw just make something up i guess

anyways, lunatic cultist is pissed so he puts a curse on wof by turning him into an npc known as the guide. he still has all his memories, however is unable to talk of being wof and being killed to anyone else unless lunatic cultist allows him.

the only way guide can return to normal is if he's killed by another human, and ofc wof plays all nice when the player comes along in an attempt to get him to kill him at some point

look it makes no sense but you're gonna see even weirder stuff-
*cough* i fused the twins *cough*

anyways, eye of cthulhu kinda senses the player's arrival and their intentions and goes on a quest to kill the player before they can do shit.

btw cthulhu's body parts have like a "mind of their own" or whatever the phrase is because idk he's a god, his body parts can have their freedom

anyways, the player kills eoc and cthulhu is left blind and his only sense of navigation is through crimson and corruption. because eater of worlds spreads corruption, it helps cthulhu make its way around.

however the player is a little fucker and kills eater of worlds because they need that goddamn nightmare pickaxe, and cthulhu has no sense of navigation left.

before that, lunatic cultist kidnapped a mechanic (like in-game), and she was set with the task to build a mechanical eoc. unaware, she does the twins since two eyes are better than one, but lunatic cultist says how the bosses are not just stronger versions but also replacements.

cthulhu, in this au, only has one eye. since mechanic used all of eoc's dna on the twins, she needs to fuse them. so boom! the most creative part of this au. spaztinazer!

anyways, since eow is dead lc orders mechanic to build a mechanical eow, aka the destroyer.

during that time, player goes to the dungeon out of curiosity as the cultists left to go look for eow's dna. the old man is there to turn the player back, but they curse him and skeletron has awoken.
