Re: hard sci-fi novel

all i really remember is its ?mostly? from an aliens civ's point of view, and they encounter an earth station that is a person who became and ai and was forced to server the outer systems for x amount of years cause he fucked up. all of the humans have had major modifications, and there are factions. like a warhammer 40k orc faction who uses clones to fight the other war hammer faction. the main enemy is a precursor machine that eats all resources and replicates. so the humans unite and fight with the aliens.

also super cthulu chick who rips apart space and time cause she's looking in deep deep deep space to find cool things. she only shows up once but rips apart a massive precurser.
