there's an explicitly trans male character that channels the appropriate magic. he's considered the weird woman who channels male magic until it's dropped that satan literally cursed him to live as a woman. it's a very binary gender system but if you're going to have eternal souls, it's not an awful way to handle trans characters. there's a lot wrong with the gender politics and Jordan sucks ass at writing women so there's much riper targets to criticize the series over than this.
