'Important Note.

This Website is a work of fiction set in an alternate universe. While based on certain historical events any similarity, of characters to persons living or dead, their actions and events surrounding them are purely coincidental. Although the names of historical characters appear, they do not necessarily represent the same people we know in our reality.'
