I was wondering if anyone could tell me if there is a flag for Hammerfell and what the insignia is?
Do the yokudan race or redguards have a motto or anything specifically Ra'gada, Hammerfellian or Yokudan?
I know that Cyrodiil has the dragon insignia but i'm not sure about any of the others.

Random thought here but the name Redguard derives from Ra'gada and that sounds like the name of a sailing race, called a regata. Redguards are known as skilled sailors, if the pronunciation is the name then that was pretty clever of the creators of the Lore.

Hammerfell, at its current state, isn't really a unified nation to have a flag. Its a patchwork of City-States, each with their own unique way of doing things and culture. There are, however, two major political groups that most of the cities claim allegence to. The Forbears, for which the term Ra'Gada came from given they we're the warriors who invaded Hammerfell from Yokuda and 'Madeway' for rest of the Yokudans to come in and settle. Their insigna is a sword I believe.

Second would be the Crowns, which we're the royalty and nobles of the Yokudan's, and as obvious as it is, their insigna is the crown, or so I think.

Whilst your reply is off topic it was perfect. On another forum I've been told that apparently they don't have an insignia. Considering i was looking for something either location specific or person specific, you've just reminded me that the for the fan fiction im writing the insignia of a ship would be perfect as my characters are pirates. Thanks

P.S. there are plenty of intelligent references like that if you look close. They are cool like that

So a sword and a ship. Perfect.

Thank you
