[@ShidenBlades] I've added the following paragraph to Aedin's CS. If you could age Jaden by two years, then he would fit perfectly to the timeline. Then again, I could slightly alter the timing of Aedin's marriage if you want to play a character who is exactly 20-years-old.

"In his youth, Aedin fancied a young courtier named Luciena Cain, whose brother had been a high ranking and talented soldier in King Lewyn's army. Their relationship produced a son named Jaden, who is unaware of his background. When Aedin married Lenore of Laketown, the relationship was ended and Luciena moved to the Dragon Mountains. Aedin helped Luciena with donations to keep her silent and to provide a future for his bastard."
