So, one could be a dragon, but it could cost so many WPs that one would have to be one hell of a RPer for a long time. Just like you could probably blow up the sun for 1e9 chi of mana. Dragons are another very interesting topic, too, I'd like to mention. Height, weight, and gender and included here, which have little effect on the functionality of a character. In the game, things such as hair color and facial features will likely also fall under this category.
Age is here, as well.
Default age is young adult. One may choose to begin at an older age, which gives them more WPs to spend on other things, but affects their ability scores. Mental attributes are helped with age. However, physical ones are hurt. Professions come in now.
