Star Maiden

Question: What became of Quetzalpetlatl?

Actually, no one knows. The Codex Chimalpopoca, in its retelling of the story, relates that she was ashamed and miserable the next morning after her brother had sex with her, but it does not elaborate on what she does, instead following Quetzalcoatl as he departs. What she might have chosen to do or how she might have responded to the event is unexamined.

There are various different retellings of the story that suggest different motivations and possibilities for the ill-fated sister of the warring twins. Some stories seem to suggest that Quetzalcoatl raped her against her will, unsurprising considering the Aztec prohibition against incest, while others imply that both siblings were intoxicated by Tezcatlipoca's interference and only realized their misbehavior the next morning. There's also usually a strong stellar background to the story, with Quetzalcoatl as usual representing the morning star and his sisters, Quetzalpetlatl included, appearing as stars in their own right (perhaps the Pleides or some other famous grouping).

Since Quetzalcoatl immediately killed himself (or, in a few versions, exiled himself), it's entirely possible that his sister might have done the same, equally horrified by what had just happened. It's also possible that, if she didn't punish herself, the pantheon might have done it for her; even if she was assaulted, the Aztecs had a fairly inflexible zero-tolerance policy for illict sex, and Tlazolteotl, punisher of sexual misconduct, might very well have inflicted some Justice on her or instituted even more direct forms of chastizement. A Justice boon might have put Quetzalpetlatl out of commission for a long time, and she certainly wouldn't be eager to mingle with the rest of the pantheon even if she went unpunished; the social stigma against her, a woman who not only had out-of-wedlock sex but with her own brother, would be massive and unforgiving.

Because of her connection to stars, Quetzalpetlatl might also have left the pantheon entirely, to follow so many other celestial Aztec figures into the waiting arms of Tamoanchan. While she isn't specifically said to be related to the tzitzimime the way some of the other gods are, she would theoretically be Mixcoatl's daughter if she's Quetzalcoatl's sister, and if her pantheon rejected her (or refused to take action against Quetzalcoatl and Tezcatlipoca, the authors of her misfortune), she might have gone to her father for comfort and asylum. That doesn't necessarily mean that she's a hostile enemy, but she certainly could be. The lady definitely been done wrong.

If you want to get even more wacky, she could even be living with the K'uh; Quetzalcoatl did spend a lot of time hanging out with them back in the day, after all, and you could even say that the disaster with Quetzalpetlatl was what caused him to abandon the Maya gods and move north to become permanently part of the Aztlanti. There is at least one Maya myth about Kulkulkan and an unnamed sister whom he abandoned when he had grown too large for her to take care of anymore, which might be considered a less violent mirror to the Aztec story.

Or she might still be somewhere in Acopa, to be found and spoken to by Scions intent on involving her in their schemes.
