Ritz Tower was the only luxury real estate property not owned by the Sorvix. People living there engaged each other in dinner parties that were, in reality, fights to the death. The winner received the better apartment. The original permits were in the name of Zaheed Shah, but Bilis Manger took over all the paperwork and designed the building to harness the power of human aggression in order to open the rift and send a message to whomever the Sorvix fled from, wanting them out of Cardiff. Dinner party served exactly this purpose.
When Sandra and Andrea tried to kill Colin Colchester-Price, St John Colchester killed them, supplying enough aggression energy for Bilis to send his message (AUDIO: A Kill to a View) to God. (AUDIO: Future Pain)
