Amending the Keeper Timeline Leading to Sophie's Birth
There is the problem of whether ages given are counting from inception or birth, so that clouds the situation. I decided to ignore that aspect, since it makes any consideration of the timeline too complicated.
Note: As stated in a comment, the elvin counting system is irrelevant. It only impacts Sophie's age. All other ages are elvin. The only difference is that Prentice would have been exiled early in Sophie's first year via human age and late in her first year via elvin age. Either way, Prentice was exiled during Sophie's first year.
Alden has been searching for Sophie for 12 years (Keeper, page 10), which is when Prentice’s mind was broken. Jolie had been dead for 15 years (Keeper, page 128). We can infer that Jolie died 3 years before Prentice was exiled. Prentice was apparently exiled when Sophie was a baby.
Sophie is 12 at the start of Keeper.
Wylie is about 20 (Exile, page 449). Sophie thinks Wylie would have been 7 or 8 when his dad was exiled. It is confirmed that Wylie was 7 in the registry files (Unlocked, page 158).
This makes Wylie 7 years older than Sophie. Even though Wylie is just 5 levels ahead of Sophie at Foxfire (Everblaze, page 129), it's reasonable that he can be as much as 7 years older than Sophie, depending on his and Sophie’s exact ages. Students in the same year in school are born over the course of one year, so students in the same year can be as much as one year apart in age.
Sophie is 13 (Everblaze, page 228). Since Exile and Everblaze occur over just a few months, we can infer that Wylie is about 7 years older than Sophie from that as well.
Stellarlune is around 2 1/2 years later than Keeper using this page as reference:

This would make Wylie around 22 since Sophie is likely 15 ½ in Stellarlune.
Prentice recruits Jolie to the Black Swan when Jolie was in her first elite year at Foxfire (Everblaze, page 529). She died 1 year later. Prentice showed Jolie a scroll written by a ogre in order to convince her to join the Black Swan (Everblaze, page 530).
Caprise Redek suffered a brain injury when Marella was "barely a toddler," which is age 1 (Neverseen, page 525). She fell from a balcony. Fintan later suggests that he knows something about what happened, so Caprise's death must tie in with the previous events.
Marella and Sophie are supposedly very close in age, so Caprice's injury occurred probably when Sophie was 1. However, that would be elvin years for Marella, so Sophie would have been a baby in human years. We can place this event in Sophie's first year of life.
Cyrah Endal died when Wylie was "barely eight years old" (Unlocked, page 159). Fintan planned Cyrah's death, and Gethen killed her by distracting her as she leaped.
My adjusted timeline:
- 4 years before Sophie’s birth: Prentice is recruited as Kenric’s Keeper when Wylie is 3 (Stellarlune, page 248). Jolie is recruited to the Black Swan by Prentice.
- 3 years before Sophie’s birth: Jolie dies.
- 2 years before Sophie’s birth: Oralie is recruited.
- Sophie’s birth: Wylie is 7.
- During Sophie’s first year of life (birth up to age 1): Prentice is exiled. Caprise Redek falls from a balcony and suffers a brain injury. Cyrah Endal is killed.
Speculation:
I currently suspect that the Forgotten Secret with Kenric, Oralie, and Fintan takes place during Sophie's first year of life. Prentice's mind had probably been searched by Gethen, which is what caused Prentice to call swan song. Kenric was checking to see if any information from Prentice about Elysian or stellarlune had leaked to Fintan.
