Ok I'm gonna try to write this as coherently as possible, but it gets complicated. Dividing by chunks to hopefully make it easier
Ploversky and Icebrook had a daughter named Streaktail. This daughter was murdered by Milopatch (a former kittypet), who then became Ploversky's mate and had two kits with her.
The kits they had were Antlerrunner and Quailheart.
----------------
Quailheart became mates with Downtooth and with her, had a single kit: Dovewhisker.
Antlerrunner mated with Bethany, who was cheating on her actual mate, Fleckheart. With Antlerrunner, she secretly had Raggedkit, Wetswan/star, and Bramblespeck. Fleckheart thought they were his and raised them as such.
Fleckheart and Bethany then had their own litter a while later: Magnoliawing and Crookedpaw.
----------------
Magnoliawing murdered Antlerrunner, the cat her mother cheated on her father with.
Magnoliawing was murdered by Dovewhisker, her half-cousin(?)/Antlerrunner's niece.
----------------
Bethany, during the affair, murdered Amberpaw, Downtooth's sibling and Dovewhisker's aunt.
----------------
Milopatch became mates with Flailshiver after Plover died, but died before she gave birth (he died from a claw wound while saving Dovewhisker from an enemy warrior). They had Orioletooth.
----------------
Antlerrunner became mates with Civetbelly, a medicine cat (their relationship was secret). They had Frogdapple.
Frogdapple was murdered by Redmoss, Dovewhisker's mate.
