Thanks guys!

@Jaxilon - the equation is the easter egg - so you found this one. It refers to a secret about the design of the game world and ties into some of the map decorations.

@Eilathen - no worries about the Kickstarter - it was well and truly funded, and they'll certainly be producing a setting book. A certain amount of that will have system specific crunch as this is a Pathfinder setting, but there's a hell of a lot of mythology and non system specific content in there too.

@Ramah - it was the best Arabic-esque font I could find that the publishers also liked. There seems to be a dearth of decent Arabic script hands with a roman alphabet, and my handwriting is not up to the standard where I'd want to try it from scratch

@arsheesh, GP - thanks!
