Unfortunately, hardcover + premium color is quite pricey on Amazon.

Reusing/stripping was one of the implicit goals of the module, so I am glad you spotted it. The Royal Quarters, Winter Palace, Crypts should be easy to lift and expand as necessary.

If you run whole or parts I would love to know how it worked!
