thinking about my a feast for crows margsei omegaverse au, which centers on two core premises:
Cersei is studding
→ the transformation is gradual and very reminiscent of hrt transitioning. it ignites cersei's libido + causes some minor physical changes, ultimately leading to her first rut → on top of the canonical themes of distancing themselves physically and emotionally, Cersei also sends Jaime away to Riverrun to purposefully elevate her chances of becoming an alpha (as in, she tries to artificially create an environment to stud herself after Tywin's death, an alpha, and her relationship to Taena, an omega) → the way she perceives it, Cersei was always meant to be an alpha, but Jaime was holding her back. enters her motif of gendertrouble. → Cerseitaena sex scene is also very related to this, since Robert was an alpha and Cersei realizes she's becoming one, which puts her uncomfortably close to the position he once occupied in her life.
2. Margaery has her first heat
→ Cersei views her as purposefully trying to seduce her, impregnating her castle with her filthy scent, tempting innocent Tommen with all her flamboyancy.
→ Cersei fantasizes about claiming Margaery and relishing in her own newfound power and societal hierarchy. Knows that Margaery will never have this
feel free to send asks if you're interested in helping me build this fic :)
