In Runemarks[]
Church of the Holy Sepulcher, Harris mentions the church of St. Sepulcher as being in World's End.
World's End is, and always has been, the centre of Order. Within the city, the Laws are followed to the letter, with no exceptions. Dreaming could be enough to be Examined, or even Cleansed, which is their euphamism for hanged. Women cover their hair, and most boys leave their families for the Order. The people of World's End pray daily and worship the Nameless.
In Runelight, it is mentioned that a plague swept through World's End sometime between Runemarks and Runelight. However, people still worship the Nameless, even if it hasn't done them much good.
