Reddit reviews RuneScape: Betrayal at Falador

There's a book about RuneScape you can read: https://www.amazon.com/RuneScape-Betrayal-T-S-Church/dp/1848567227

Someone also made a PDF of RuneScape history. It has over 400 pages. Very interesting read.

EDIT: There are 3 books you can read. They are all on Amazon. I believe they are also canon.

• Betrayal at Falador
  
• Return to Canifis
  
• Legacy of Blood

I'm not sure when you read it, but could it have been something in the RuneScape series? Particularly Betrayal at Falador?

>In the kingdom of Asgarnia, though the Knights of Falador defend the land a protect the people, they face threats that clamor from all sides-and from within. Enemies mass at borders, and a killer stalks the night killing innocents and slipping away unseen.

>When a young woman appears in the teeth of the storm, her sudden arrival launches a chain of events that endangers the very fabric of magic. And unless the knights can solve the riddle of Kara-Meir, everything they hold close may be lost.

Dynamism

This seems relevant.

This one's probably pretty great too.
