The Modern Crown was the royal crown, created in 2648 for the Enkland Royal family after the original crown was lost at sea.
The Crown was created in the royal forgery in 2648. The original crown had been lost at sea, so a new crown was made for the coronation of King George III. It was worn by every monarch since it's creation for 143 years: 4 kings.
The original crown that was lost at sea was found in 2792, whilst King ewan was on the throne. Ewan decided that instead of replacing his crown, which was nearly 150 years old, he would melt both of them down, and then create a new crown out of The Modern Crown and The Royal Crown, bringing together all the kings and queens of Enkland once more.
