Could I have all of the PC's email me some thoughts about their respective homelands so I can get a feel for it. Its history, culture, laws, people, or anything else that you think sets it apart, or that you find significant. (Even though it may be destroyed - for flashbacks or to have a better handle on where your character came from.) If there is a tone or flavor associated with it that is good to know. I have some info from your repective histories and IC stuff, but more is better. If, and when, you have the time this would be great. As much or as little as you like. If you want to leave it completely open for the DM and I that is also fun.
Classes, feats, languages, or prestige classes that are common for your lands. As much or as little as you like.

Thanks!!
What ever you send to me I will make available to the DM and if you do not want something to be put into a narrative without you being prepared for it let me know as well.
Here is a basic example:
Barrowshire
Tone/Flavor: Bright, happy, carefree, competitive, friendly, open, helpful
Notes: Familes have long hsitory of Lorekeepers. Families specialize in an area of knowledge. Family sages compete to be useful to adventurers and others. A large transient population of adventurers and people needing the help of sages. Otherwise a typical halfling shire. Quiet, calm and relaxing. These halflings do have adventures an knowledge does not always like to be found and adventurers do bring adventure with them.
