Often established on highly civilized planets, The cathedral serves its religion as a meeting place for devout followers of his or her religion. Big enough to host even the biggest meetings, communal service often lasts for whole days. As is usual with religions, Cathedrals also house large libraries filled with books containing religious texts, scholars who participate in the brave endeavour to read and understand these texts often end up as clerics, proficient in bringing forth the message of their religion in a way that captivates many. It is true that every religion benefits from a cathedral, as it is a way of showing just how prosperous the religion is.
