My personal version of this headcanon has Discord in the role of Morgoth. My idea is that the Changelings are the mutated descendents of the pureblood alicorn tribe referred to in The Journal of the Two Sisters. Discord mutated them into horrors for his own amusement, perverting their biology so that they have to consume others' love to live. It is possible that Chrysalis may be one of Celestia and Luna's family, driven insane by Discord's tortures and barely remembering her kin as anything other than obstacles in her way.

It was one of his taunts to Celestia and Luna - to turn their family and kin into monsters. Now, millennia later, it seems that at least a few of  them are choosing not to be monsters.
