The story starts in autumn of 3630 when Emery leaves to go on her journey and then takes place over the course of the next decade or so. At the start of things, the ages for the main characters are:

• Emery – 13
• Gavin – 12
• Renato – 12 (but almost 13)
• Tipha – 13
• Ulyssa – 17
• Draco – 15
• Roy – 13

For (some but not all) secondary characters:

• Sage – 10
• Scout – 10
• Alton – 10
• Celeste – 8
• Branwen – 8
• Cormag – 8 
• Levi – 14
• Rhys – 15
• Alphonse – 14
• Tanith – 10
• Balthazar – 9
• Solomon – 11
• Kiran – 21
• Maia – 21
• Jasper – 21

There are too many secondary fankids to list them all, but these are some I know the ages of. There are others who I’m still working on, since my timeline is still in development. Many of them start their journeys quite a ways into the plot, but all play an important role!
