Oh let me see if I can grab something from Felyn to tell you about that isn´t super depressing,, anything regarding his backstory is just pure neglect and repressed depression on his part so it´s not really the most fun to get into the nitty gritty unprompted haha.

But the general gist is that he grew in a super super strict and religious noble house in Menzoberranzan, where he idolized his matriarch to the point of believing that she was an avatar of Lolth herself. So he tried to do anything and everything to please her, to gain her affection- failed miserably bc she didn´t think he was special enough, just a lil ant to her. 300 years of servitude and pretending to be something you are not to fit the societal standard he was supposed to fit (A strong leader, fierce and harsh, not giving into anything but his own ambitions... and being a woman, big reason he didn´t transition until post game)

A fun little positive thing I can tell you though is that Felyn adores cuddles, back home in Menzoberranzan he was forced to sleep with one eye open and wake up before the light. So now that he is just traveling around doing whatever he wants, he loves sleeping in, staying in bed for as long as possible and cuddle with those he loves (platonic and romantic). To him there is nothing that feels as safe and comforting as laying in bed with someone you cherish, holding them tight and enjoying the warmth of the blankets and pillows.

(also thank you so much, that´s so nice of you!!!)
