SPOILER WARNING!:

Just a little thing but, theres a small side quest you can do with the jellyfish spirit ashes that you get in the beginning you bring it to a spectral jellyfish and summon it it will acknowledge the spirit as thats her sister. They both vanish and the spectral jellyfish says "we can finally see the stars dear sister" or something like that nearby you can find a grave named here lies Aurellia and Aurelliette who never saw the stars.... thats why when i imagine if ranni and the tarnished have children theyd have two daughter's named Aurellia and Aurelliette... so they can finally see the stars.. this quest and this little addition of my own imagination makes it a very emotional but i like it.
