I have an LJ account strictly in order to participate in LJ comms. The only ones I'm active on are those devoted to the Sansa Stark/Sandor Clegane pairing. I accept all friend requests but this journal is a bare-bones affair. Alas, I'm not a member of today's tech-savvy at-risk youth demographic, so have little to write about. Sansan is my first and only serious ship (though I had a puppy love for Mulder/Scully back in the day).
I recently started to write Sansan fanfic. They're all chill fanfics with a lot of smut and character analysis. They combine my interest in canon asoiaf, fairytales with female protagonists as the wily storyteller rather than the damsel in distress, history, mythology, feminism, first love, and men who do not conform to romantic tropes (especially those involving hypergamy).
I'm humbled if you care you read them, let alone like them! You can read them at Fanfiction.net and Archive of Our Own.
