The capital of the Church and the cradle of humanity. The planet is overcrowded; teeming masses of the faithful squeeze into the cities that dot the globe. This is partly because vast regions are given over to wilderness and allowed to exist in their natural, unterraformed states as an example of the Pancreator’s bounty. Permits to visit these wildernesses are allowed, but overstaying one’s allotted time is a crime, prompting manhunts for any recalcitrant hermits. Immigration is strictly controlled by the Church, and those born on Holy Terra are given special consideration over foreigners. It is the prime planet for pilgrimages, however, as holy sites important to human history are found on every continent.
The Patriarchal Seat (some say “throne”) is always situated here, usually near the birthplace of the reigning Patriarch. If the Patriarch was born elsewhere, he chooses the seat’s new location based on rather complex readings of ancient texts and affinities for local saints. Most, however, simply inherit their predecessor’s seat, which has been in Rio Brasilia for the last century. The Church’s grand archives are spread throughout the world.
The planet Mars hosts one of the most popular pilgrimage sites: the alleged birthplace of the Prophet. Little actually known of Zebulon’s early years, and many worlds during the Second Republic claimed his natal spot (Sutek, Grail, Malignatius). During the Dark Ages, however, the Patriarch declared Mars the one and only true site of Zebulon’s birth.
