>the plot of borderlands 3
Insanely, considering its length, fuck all actually happens in BL3.

Here is the entire story;
>The Vault Key is missing, better find it
>There is a new cult called "Children of the Vault"
>They follow two Siren Twins, who can absorb powers of sirens or people or monsters they kill.
>They want to find and open the Great Vault
>The Great Vault contains the Destroyer (BL1 final boss) who is a universe ending threat
>You travel various planets gathering vault keys
>You kill one of the twins
>You hunt down the next one on the homeworld of the Eridians (the guys who built the vault)
>Turns out Pandora IS a Vault
>And the Vault Key is the moon, Elpis
>Moon is activated by the other twin, Pandora is opening
>You kill the other twin+the destroyer again
>Lilith """sacrifices""" herself to seal Elpis to stop it destroying Pandora

>also this shitty annoying siren child called amara is there, Maya (BL2 siren) dies to save her and later Amara gets her powers
>also Tannis is a siren

So opening BL4, everything is sorted with the Vaults, more or less. Great Vault sealed, other vaults found/opened, Lilith """""""""""dead""""""""""""", rest of the gang chilling out around the universe.
