Private Background
Along with the publicly viewable public background, you will also write a private background for your character. This is viewable only by yourself and SoA staff, and should consist of a more comprehensive biography of the character. Your private background is set during character generation and cannot be edited afterwards, but if you want to update it after playing for some time, you can submit proposed changes to staff.
Some important details for a private background might include the character's birthplace and parentage, influential people and events in their life, and some of the interests, goals, and fears that presently drive them. Staff may use your private background to tailor events to your character, so if there is anything in your character's present or past life that you would like staff to be aware of, this is the place to put it!
