The Revolution was when the ancient rulers were overthrown by their slaves. The slaves realized the power of technology and utilized it while there oppressors had no clue how any of it worked or how to defeat it. So, the slaves had a uprising and were able to become there own people and spread. War spread across the entire land. A major landmark of this time is the Darakyon Forest . It is what the slave kinden were trying to fight against. After the revolution the term "Apt" and "Inapt" was created to seperate the group of kinden that understood technology and the ones that didn't. This was a pivotal point in the world and many years later the Shadows of The Apt series takes place.
