Characters

You can have up to 9 characters at any one time; if you wish to have more, existing characters must be removed. Once you have created your initial character or activated a character, you can return back to the initial state by choosing Options from the HUD dialog to create additional characters or assume the identity of an existing birth.

There are four stages of aging: Child, Adolescence, Young Adult, Adult. Fertility begins sometime during the Adolescence period. Aging is based on species (different for each species) number of days till you are considered a full adult. You are able to fully use the HUD at any of these stages.
