We are building a castle. Every self respecting castle has a Coat of Arms, right?
If we had a Coat of Arms for the Citadel what would you like to see on it? Now keep in mind the definition of a Coat of Arms according to eHow is:
The use of coats of arms became popular in Europe during the Middle Ages, as a means of identifying individuals and families. Heraldry developed to keep records of the genealogies of families using coats of arms, and many of those genealogies still exist. Today, heraldry is not regulated in most countries, and there are that sell decorative "family crests," complete with an ancestral history of the surname.
