It's been on my mind for a while but are there only men in the Vostroyan Firstborn Regiments or are there women too. I've seen the pic on the Vostroyan Firstborn wiki page on this site which shows a female medic. Now this kind of answers my question but at the same it doesn't because the wiki page doesn't say anything about women in the regiments. The wording within the page clearly talks of Firstborn sons yet doesn't include daughters. So that would mean no women join yet that pic clearly shows that they do so I'm at a lose as to what to think. I really want to know because I have a few characters I want to make for a story but I don't want to write something that not accepted canon so any information would be appreciated.
