Just a warning: This lot is HUGE, and file is 24.5 MB, so you have been warned! :)
The Lot is 5x6 and is furnished, but not decorated too heavily (but still has the biggest CC list yet).
There is a folder of CC in the RAR that you will need, in addition to what is packed with the lot itself. Make sure you install the two scriptorium staircases properly- The Original RARs for these are inside the CC folder.
