Nagal Residence
The Nagal Residence was the gigantic, lavishly-appointed home of the Ferengi Grand Nagus. It was located in the capital city of Ferenginar, with a view of the Tower of Commerce. 

It was said that even the waste extraction fixtures were plated with latinum. Quark planned to replace them with solid latinum fixtures when he thought he was going to become the next Nagus in 2375. ()
