The Pendragon Adventure/Fridge

Fridge Brilliance

 * In The Pendragon Adventure, the Big Bad of the ninth book, Raven Rise, is named Alexander Naymeer. I realized why his last name sounds so weird: It's "name here"! He was raised in an orphanage! - Kilroy Was Here

Fridge Horror

 * In the tenth book, Press reveals that in all of Halla, there are seven worlds on which intelligent life has evolved. This becomes very grim when you remember that Halla is everything that is, has been, or will be, meaning that there are only seven worlds with intelligent life in all of eternity. What happens when they're gone?
 * ^This is why a sense of scale is so important.
