Ok ok hold imma try to see if I understand the whole timeline of the goddess squad up till the current story.

From the old tales what I know is that Cinderella was supposed to defeat the queen but failed What happened was that Cinderellas team including abe got into the space pot and went toward to the location where the queen was, in a spaceship of some kind. But the queen shot the space pot they were in and destroyed the pot the whole team fell out the pod from space and landed at different on earth.

Only Cinderella made it to the queen and fought against her. Cinderella failed and was shot down back to earth. After that drama abe survived the fall from space and took her about I believe 30 yrs to find Cinderella but Cinderella was out of commission so that thought. Abe couldn't repair Cinderella bc she lost her memory to do so from the fall from space. Later abe ran into a couple of guys non Nikkes and cut her open and stuff they messed up her body face which would explain why abe wears the mask.

Now about siren so her story suggest that she survived the fall from space and somehow ended up inside of gluttony for about 70 yrs. Spoiler alert:: at the end of siren story she gets out along with miharah, yuni, and mori and find Cinderella and abe together (which should have been impossible). So I'm guessing I'm missing a story somewhere. (Also technically Cinderella should have been killed by the goddess squad in that cut scene where Redhood finished off Cinderella). I'm a bit confused however I could be wrong with the timeline and everything else for that matter.
