The history can be divided into three eras of the Gregorian Calendar:
- The First Era (F.E.) is the era of prehistory and much of antiquity, also known as Before Common Era (BCE).
- The Second Era (S.E.) is the era that began with the birth of Jesus, also known as Common Era (CE).
- The Third Era (T.E.) is the era that began after the end of World War IV.
Second Era (S.E.) Edit
- January 5: The Paris Opera House, known in the Second Era as Palais Garnier or Opéra Garnier, opens its doors.
- World War I takes place.
- World War II takes place.
- December 18: The Moon Treaty drafted by the United Nations to turn jurisdiction of all celestial bodies (including the orbits around such bodies) over to the international community is signed.
- World War III takes place.
? S.E (centuries before T.E.)
- Luna, known in the Second Era as the moon, is colonized by a small group of researchers from many different Earthen countries in order to further space research and exploration.
- Sixty years after colonization, Luna is recognized as its own country, a republic, with numerous Earthen countries and cultures residing there.
? S.E[note 1]
- Cyprus Blackburn, after his DNA is damaged from exposure to ionizing radiation as a child, is the first Lunar ever to have the Lunar gift of bioelectric manipulation.
- Blackburn becomes the leader of the Republic of Luna. He turned the republic into a monarchy and became the first king of Luna.
- The relation between Luna and Earth becomes strained as Earthens grew suspicious of Blackburn's ease to change the country’s political structure.
- Blackburn's Lunar gene is inherited by his children. For a few generations, the royal bloodline was the only bloodline that included the gene. Due to the royal family's notorious promiscuity and abundance of illegitimate children, the gene became more common with each generation and eventually becomes dominant within the Lunar population.
- The belief that Lunars would lose their gift if someone not of the royal bloodline sat on the throne becomes popular. The crown encourages this superstition. Royal scientists "prove" it's veracity, and anyone who suggests otherwise is jailed or executed.
- Hormesis begins to develop within the Lunar population, a genetic mutation that resulted in one's inability to output or receive electromagnetic stimulation from others. Lunars born with this mutation are called "shells."

- ↑ It is unknown whether the following events occur in the Second or Third Era.
- ↑ This happens after January 3, 113 T.E., when Winter has already turned 4 years old
- ↑ While Linh Adri claims that he caught the plague on his trip to the European Federation to pick up Linh Cinder, this seems highly unlikely. She later accuses Linh Cinder of exposing Linh Peony to the disease, with the alleged window between infection and symptoms in that case being either minutes or hours, not over two weeks. In short: no timeline should be made based on information from Linh Adri, especially when she's trying to suggest Linh Cinder is at fault for something.
