Enhances LARP by allowing the Captain to dress like Napoleon. (#96156)

## About The Pull Request

My antagonists are many. My equals are none. In the shade of tendrils,
they said Lavaland could never be conquered. In the land of wizards and
operatives, they said Space could never be humbled. In the realm of
wolves and snow, they said Icebox could never be tamed. Now they say
nothing. They fear me; like a force of nature, a dealer in thunder and
death. I say, “I am the Captain.” I am emperor.

## Why It's Good For The Game

We have pirates in 17-19th Century gear. The HoS has a Shako from the
19th Century. Let the King of Kings get in on that action.
