GROUP NEWS: Updated Shield and Blade Bios

We've updated the Shield and Blade entry. After hearing some people's impressions of the groups, we decided we needed to rewrite their descriptions to better portray what they stand for and allow people a proper understanding what they are stepping into.

Sorry for any inconvenience. If you decide to change sides and have already drawn your OC but don't have time to redraw them for some reason, feel free to note us and we can try and work something out.
