Sorry Hussar, I am confused. I don't think I ever mentioned anything about not giving the player the history, locales, geography, etc of their home if they asked. I am pretty certain I said the exact opposite. I was speaking about players that don't want those things. They want no part of it. If you are referring to them writing a paragraph or two. Sure, it'd be welcomed. I don't know of any DM that would turn that down either as long as it followed the theme/premise/etc. of the world. For example, this is like Hyboria, then the player insists on them being from a crashed spaceship. Cool idea. But if the DM shot it down, they should be fine with it.
