There is no mention of the Changeling anywhere.
A Long-Awaited Drinking Party is apparently official.
No one is born with magical abilities. They must be learned.
The book speaks of Balmung as if it were still intact. Presumably it was magically repaired.
--More on the Fallen Lords
The Leveller is referred to as the god who created himself.
Soulblighter was not an archmage in TFL. He was merely a magically enhanced warrior who could turn into crows for some reason. (The only appearance of shape-shifting in Myth.) He became a powerful sorcereror in record time during the sixty year gap between games. He has also been refered to as Anshar, patron of the hanged.
Balor was the first to call Myrdred the Deceiver. His honorific, "Source of the 500 Poisons," refers to his tendency to betray allies. He reportedly has the Confinement Dream, and was probably the one to cast it on the Watcher.
It's the ghôls who maintain that Shiver is Culwyeh. What sort of history does she have with them? It also says she was probably the most powerful sorceror around during TFL. The whisper dream was also called the nightmare dream and forces the target into a dream duel ala Freddy Krueger. Rabican apparently beat her here by exploiting her weakness.
The Watcher is called the Mad Goat of the Fens because he was insane.
The Lurker was also known as Bheil, the twice-born daughter of flood and famine. That means two of the fallen are called twice born.
The Voiceless One was called Ravanna, the loveless child of the unwed dawn. Deceiver refering to Shiver as Ravanna is what sparked speculation that they are connected, possibly the same.
Contrary to my previous post, the book says the last fallen lord has yet to be revealed. That means Shiver has to be the Voiceless One, though this was not common knowledge, even though the existence of both was known. Obviously, the unrevealed one is the Faceless Man.
--Observations
The Voiceless One's honorific, "Loveless Child of the Unwed Dawn," sounds much like the honorifics of the Mahir.
Bonesplitter seems like a Myrmidon name, but the book says there are no recorded Myrmidon mages, though such a thing would be possible.
