Tale Foundry Timeline

An Age is used as a measure of time, roughly 500 years in the realm of The Ander Vale. (Only events relative to the prompts are included)
Age of Dawn: Old Havenwood is established. Hjall Vord convinces them to build the well, which starts the destruction of Old Havenwood and the birth of Havenwood on the other side of the forest. The Line of Decay is created, and slows to an impossible to see crawl. From then, it is monitored heavily in case it spikes.
Hjall Vord vanishes, never to be seen or heard from again.
Age of Growth: The Ander Vale is established as an independent country, including The Havenwood and the Havinites. The Child Labor Laws are implemented after seeing economic and cultural decay. This successfully remedies it.
The Well of Youth begins being regarded as a legend than a part of Ander Vale history.
Age of Death: The Ander Vale is under civil war called The War of Innocence. The people are victories and the Child Labor Compromise is created. The children ages 11-17 go under experimentation and become G Babes. The Masks are created. The decay returns in a lesser form.
G Babes are integrated back into society on command of The Masks.
Age of Music: A renaissance period for The Ander Vale. Many young people of the arts showcase their works, inventors get to work, and progress is seen.
Age of Brass: With the fading of art and inventions comes an age of technology. Steam power is popular, electricity is recently invented, as well as mass production and factory work. This is the current age.
The Line of Decay has moved significantly for the first time in hundreds of years.
