ENTRY 08: SPIRIT JELLYFISH
Now is as good a point as ever to finally address the fact that Elden Ring is set in a time and place where the processes of death itself are pretty much broken. Everybody living in the Lands Between can technically be considered immortal, immediately resurrecting or reincarnating every time they're killed.
The specifics of this are ambiguous - like most things in the game - but the jellyfish are implied to be a form taken by souls in some kind of limbo-state between death and rebirth, but only the souls of human children for some reason.
The specific jellyfish you acquire as a summon (and she's not a bad fighter for the early game!) is named Aurelia, which is funny because that's also the genus containing moon jellies. Did she pick that name after becoming a cnidarian, or is it just a popular baby name in the Lands Between, possibly among parents with a sick sense of humor? She misses her twin sister, Aureliette, which is an even funnier name in light of all this, whom she had promised to stargaze with once they turn fourteen.
You can bring Aurelia to Aureliette for a sweet and touching reunion, but don't worry; you won't lose the summon, so you'll always have the soul of a dead kid ready and waiting on speed dial to wail on the local wildlife.
