  4. The diary entry of Prince Nile in {S} Icicle Bay Getaway states that the Decade of Peace was the first peace agreement between the two races in about a century.
  5. In {s} Icicle Bay Getaway, the biography on Ruta reveals her birthdate.
  6. Based on Nights' art of the previous monarchs, it can be assumed that the Queen was born in the same year that the Vibrant died.
  7. Nights mentions that Suvillan's birthday falls on the same date as the webcomic's anniversary, 5/17. Furthermore, a banner shown during the birthday festival preparations says 'Happy Twenty-four!' in monster script. If the current year is 4529, then this means that Suvillan IV was born 24 years earlier in 4505.
  8. Solis' age is given here.
  9. In the panels showing Meimona's birth, she is adopted by an unknown winged woman.
  10. In {s} Icicle Bay Getaway, Meimona tells Nino that she is 19 years old. If the current year is 4529, then she must have been born nineteen years ago in the year 4510.
  11. Nino himself says he is 18 years old here, and in {S} Icicle Bay Getaway. If the current year is 4529, then he must have been born eighteen years ago in the year 4511. Nino also recounts his birthdate to be on the 11th of Ruby Sear after examining the Zodiac book in Icicle Bay's library.
  12. 12.0 12.1 In {s} Icicle Bay Getaway, a book in the library mentions that the winged prince passed away soon after writing his journal entry on the creation of the peace treaty. The journal entry is written on the day the treaty was formed, 17th of Jade Harvest.
  13. The book Rigmarole of Oshen in Red Tulip town's library mentions that humans and monsters saw a decade of peace. A ten-year calculation shows that the decade of peace must have started in the year 4513, exactly ten years before the peace treaty was breached in 4523.
  14. In {s} Icicle Bay Getaway, a book in the library mentions that Suvillan III personally sought assistance from Prof. Zachery after the creation of the peace treaty.

  18. Kaji's banishment has been stated to have happened six years ago, and it's assumed that it occured not long after the coronation. Incidentally, 4523 would have been the year the Queen would have come of age, at least by the standards of human society.
  19. Kaji’s flashback shows that it is raining and that the water level is quite high by the time he wakes up. Additionally, the Barrier is bathed in a red glow closer to the horizon, meaning Kaji arrived in the human world after the Great Flood and just before the creation of the Barrier.

  24. In the panels where Aria recounts Kotori's visit, her calendar displays the year 4528.
  25. Kaji has apparently been dealing with Meimona's thievery for approximately one year.
  26. Since the creation of the dome and barrier is stated to have happened six years ago in the story, and in {S} Icicle Bay Getaway, a book in the library dates it to the year 4523, a simple calculation concludes that the current year is 4529, six years after the barrier was made.
