Whenever I write backstories, I like to be careful not to add too many details which stand out as possibly being "gimmicks", or details that are unnecessary to the story itself and just added in for a cool factor. A few things I'd suggest thinking over are: "What's the inspiration for having colour-changing eyes? Does it do anything for the story-telling aspect that simply saying she 'hulks out' can't already cover?" A character with an out-of-control rage streak would be pretty awesome, but another thing to consider on that note is how she killed seven men without so much as a scratch with casual training from her lover, who could not kill a single one himself. That might be a bit unrealistic, and it could contribute more to the story to have the deep-set angst and grief of not being able to avenge her dead lover, the hatred of self for being too weak at the time, inspiring her to go on and become a better fighter to kill evil men like that.
I believe Pegasuses are also only found canonically in the Diadem, named such because the location was recently found and claimed "so beautiful, it was a Diadem fit for Gods". It's considered terribly dangerous and only accessible by airships, which does beg the question of how a brothel owner might get their hands on one.
