Hello Young Pope and welcome back to the game! In response to your question, the first thing you should know about the Hosian Churches is that the Selucian Patriarchal Church (FKA the "Selucian Catholic Church") and the Theognosian Church (FKA the "Orthodox Catholic Church") have been merged as a result of the Second Council of Auroria (RPd
here, wiki page
here) and are now a single body, the
Aurorian Patriarchal Church (APC).
If you want a brief overview of the current IG equivalents of RL concepts, places, and things, including the one highlighted above, check out
this list. A more detailed list of Particracy's religious denominations, including their RL equivalents, is on
this wiki page.
And if you are interested in RPing with the Arch-Patriarch of the Aurorian Patriarchal Church, let us (the RP team) know - we have the authority to control the leadership of the largest religions, especially the APC.
