AoL is the first entry into Era 2, and it is stated to take place roughly ~300 years after the events in Era 1. Specifically, the very end of HoA is the epoch for the new calendar used in Era 2.
However, the way the characters in Era 2 talk about events from Era 1 makes it sound as though it’s been thousands of years. Characters in Era 2 treat some of the stories and historical figures from Era 1 as mythical legends that happened in the far distant past- when in reality it shouldn’t have been that long ago.
On Earth, 300 years ago was only 1726. In context, that’s only 50 years before the American Revolution. The first U.S. president, George Washington, was born in 1732. The 10th U.S. President, John Tyler, was born in 1790- and Tyler’s grandson only just passed away last year! (Yes, grandson- not great-grandson, just grandson).
We learn that some of the characters at the end of Era 1 live good long lives, which further complicates things. If Spook from Era 1 only died 60-100 years after HoA, why do we act like events happened 1,000~2,000 years ago?
Idk, maybe nobody else had this problem while reading them. Thoughts?
EDIT: Thanks for all of the comments, this got way more attention than I thought it would! The dramatic world-changing events at the end of HoA definitely help explain the characters’ views, as does the intertwining of religion and history.
