The Hall of Faces was the great hall of House Catherion's chapterhouse. Upon its escape, a babel massacred the occupants of the House and placed their skulls on the benches of the Hall of Faces; on the benches opposite their crania, it precisely arranged a collection of animal skulls. The Book of the War compared this arrangement to the Parliaments of Faction Paradox and the Celestis. (PROSE: The Book of the War)
