Personal history
Not much is known of Renatas past outside of her Kaedran heritage, and she hasn't been particularly forthcoming about her early life herself. Given the way she carries herself, as well as her focus on targeting ships of Kaedran origin, it's rumored she may have come from a minor Castainian noble or merchant family that had been disgraced in some way.
What is known is that she first joined the Redwings around the age of 16, serving on the crew of the Pheonix, and eventually working her way up to the rank of captain by the age of 21. It's around this time that Renata truely began to come into her own as a member of the Redwings, developing a reputation for her boldness and cunning when she began leading many raids closer to the Kaedran territories than most other ships. This reputation would see her rise to become a high ranking captain within the Redwings, and eventually become Fleet Captain around 28. It was also around this time that she began doing privateer work for the kingdoms of Aelor, which only further strengthened her influence.
