I just wanted everyone here to be clear on this point:
The Rappan athuk bonus levels are for the Kickstarter pledgers ONLY
They WILL NOT be available in the book or for sale if you buy direct from Paizo. I know that's not fun for being a loyal Paizo customer, but that's why I'm making sure everyone knows to get in early.
PLEASE see the Rappan Athuk thread here for more information.
And thank you all again.
