Here are some one liners...
The First Multi-Alphabetic Cypher -- I talk about a code disk invented this year that will have use all the way into the 20th century with the Enigma machine. I also mention George Washington's code book again.
The Great Brotherhood War -- Galacia in Spain is a lawless region so the peasants get together and fight the nobles who are causing the trouble. I also talk about civil war reenactments and muskets.
Inuyasha and the Warring States Period -- Japan begins the Warring States period that has references in modern culture today including video games, movies and the cartoon character, Inuyasha.
