Whilst I think that the Kovarian Chapter deserves its own page, there is certainly a lot of overlap for the other three. The Church and the Papal Mainframe are the same and the page for the Silence is about both the Church and the Kovarian Chapter, seeming rather confused.

How should we go about merging these pages and what actually is the Silence? The Church and the Papal Mainframe certainly should be merged.
