The War of the Sun and Moon (Note: As we don't know the name of the Central African Moon diety, I'm going to assume he is identical with the old Egyptian Iah)
Event 1: A Realm Divided (Fires a few months after game start for the Pharaoh and vassals of him, events for one religious group alone come later)
The Garamantian nation is the pride of Africa. For a thousand years, our kingdom has stood free, rich and mighty as empires around us rose and fell. Our power is such that beyond the vast desert to our south, mighty rulers tremble and pay tribute to us. Our wealth is only further increased by trade with the coastal realms, shifting in rulership like the desert sand, between Phoenicians, Greeks, Carthaginians, Romans, and most recently the Libyan Berbers and the pale foreigners who call themselves "Vandali" or "Alani". Yet Garamantian civilization has stood firm like a rock, the secret of its success and might the vast underground reservoirs the Gods showed our ancestors how to find. With tunnels and canals we brought it to the surface and turned the desert valleys into lush lands of plenty. Knowing their entire existence as a civilized people is possible due to the grace of the gods, Garamantes everywhere are deeply religious. Yet therein lies our greatest weakness at the current. A division plagues our land, a division over the Gods.
Dismissal A: Sounds worrisome, ask the Council about our religious issues (Event chain starts)
Dismissal B: Bah, religion! The only thing that matters is the survival of your line! (Player will not get the event chain)
Event 2: Can It Stand? (Fires just after the previous)
To the west, the people and nobility worship a faith introduced by the ruling dynasty, which is said to have have been based on the faith of the mythical land blessed by Neith the Creator, somewhere to the east of the great mountains and vast deserts of the Cyranican hinterland. To the east, the people worship the traditional faith of the land, worshipping a diverse array of gods both native and brought to our lands by the Berber nomads who make up a substantial percentage of the population in the Garamantian kingdom. In the northwest there are also persistent worshippers of the solar cult of the western berber clans, so far resisting integration into the wider religious life of the realm. So far, the Pharaoh has managed to keep the realm relatively united under the Kemetic umbrella by stressing the supremacy of the common gods of all three faiths, the sun and the moon gods Amun-Ra and Iah. However, following the recent announcement of the Pharaoh's Court Griot about the legendary origins of the dynasty, this system has begun showing cracks. The Pharaoh rules the Garamantes, but is Pharaoh Garamantian?
Dismissal: Of course he is! ...Right?
Event 3: Egyptomania (Fires five years to a decade after the previous)
Since the discovery of Pharaoh's legendary ancestor some years ago, nobles all over our kingdom have ordered their own griots to examine their ancestry, consulting oral and written legends and discussing them with other griots and scholars. It turns out a substantial portion of the nobility in the west of the realm is descended (or at least so they claim) from either the same legendary stranger as Pharaoh, or his trusted companions and lieutenants. The ancestor, known as Nef'rut, was said to have come from the eastern land of plenty, a land most of the Roman and Greek traders and refugees in our country believe to be called "Aegyptus." Inspired by this supposed ancestry, Kemetic nobles pay vast sums for any Roman scrolls or books on the legendary land of Egypt. "Egyptian" clothing has become high fashion, priests dream of visiting the ancient Nilotic temples of great gods, and architects vie to construct the first Garamantian pyramid, a vast tomb structure. The Berbers and other Garamantes however feel increasingly alienated, and though the nobles would never dare speak it out loud, the commoners of the east increasingly hiss in hushed tones about foreign gods and foreign oppressors.
Dismissal: Surely it is just a passing fad, like that time people caught critters in ball cages and made them fight.
Event 4: The Double Crown (Fires about five years after the previous; should give slightly reduced Moral Authority for Kemetic and increased for Atenist)
You are in your study, skimming through a worrisome report about lowered output of water from the tunnel systems in the northeast, when a courtier bursts through the door, the guard outside failing miserably at stopping him. You make a mental note to ask the guard commander to give the guard a good beating for such incompetence, and roll up the scroll. The courtier barely bows before excitedly handing you a thick book written on calf-skin parchment. "I managed to get it, my liege," the courtier explained, "it cost me a small fortune to get it copied, but-" You dismiss the courtier with a hand motion and spread the book across your desk. The Greek text quickly confirms you have indeed got your hands on a copy of The Double Crown, the scandalous new book that spread across the realm courts like wildfire. The book, originally ordered by a member of the ruling dynasty and written by Greek scholars from Cyrenaica under the guidance of the griots, connects the legendary Nef'rut with Pharaoh Nepherites II of the Egyptian 29th dynasty. Betrayed by his treacherous general and cousin Nectanebo, he was dethroned and imprisoned at the Temple of Amun at Siwah, awaiting execution. However, his lieutenants saved him, and together they fled into the desert, calling on the gods to throw Nectanebo's family from the throne forever. Indeed, Egypt fell to the Persians a few years later. While the overall point of the book is to claim the royal dynasty of Garamantia has divine right to Egypt's throne, the furore has been caused by claims the book makes that Nef'rut and many of his lieutenants were Atenist. The Cult of Aten, recreated recently by aegyptophile nobles who considered the reign of Akhenaten the golden age of Egypt, is suspected of murdering those who believe in gods besides Aten, even sacrificing them.
Dismissal (Atenist): They doth protest too much.
Dismissal (Anyone else): Atenism in my history? I would have burned this book had it not been expensive!
Event 5: The Moon Queen (Fires about a year after the previous, slight boost to Central African MA, sets a flag that the event chain is complete)
The scribe hesitates for a moment, as he opens the banned book and sees the bloodstains from the peddler caught selling it. You helpfully remind him he will die in poverty unless he reads it out loud to you. That gets him going, and you soon confirm the rumoured contents of the book are really in it. A new hit among the clergy in the east, The Moon Queen is a version of the history of the current ruling dynasty that contrasts sharply with the stories the population hears from the griots.The anonymous author claims in the introduction that he is a priest of Ieth censored by the clergy for telling truths not in line with the falsehoods of The Double Crown, which all Kemetics secretly agree with. The official history of the kingdom states that the current dynasty was established as rulers after leading a rebellion of true Garamantes against the Libyan queen Tin Hinan, foisted upon Garamantia by the Romans, who occupied the capital of Garama and tried to establish it as "Provincia Phasania." She was thrown out and fled to a Roman fort far southwest. The new book instead paints Tin Hinan as a divine saviour, the daughter of the Mother of Creation Neith and the Moon God Iath, who had tried to live a normal life until her husband, the Roman-friendly king, was murdered by servants of the Egyptian warlords he had sent to the far western borders as march lords. Referring to her as the Moon Queen, the book states she decided to save the people from a destructive war by leading the purest and the best into the mountains to the Southwest to form a new kingdom with the Tuaregs, vowing to one day return and liberate the Garamantes. The rest of the book is a tirade against Egyptians and Kemetics, among other things accusing the royal court of creating the Cult of Aten to terrorize the true believers.
Dismissal (Central African): Could it be true? We should ask our traders to question the Tuaregs.
Dismissal (Anyone else): Surely none can believe such conspiracy nonsense?
Event 6: Abandoned And Divided (Fires under select conditions; that the previous event chain has been flagged as complete for at least a decade, that the year is after 520 (i.e. after the Justinian plague tends to hit on historical), that the Garamantian kingdom title holder is Kemetic or Atenic and does not hold Egypt, and that there are Central African landed characters in the realm)
In the last decades the situation for the common people in our kingdom has grown ever darker, despite the nobility and merchant princes continuing to live in relative safety, comfort and wealth. Plagues and diseases have wracked the countryside while harvest have been declining significantly due to inexplicable reductions in water output from the underground canals. The people claim the gods have abandoned them, and clashes over exactly whose false worship caused this get more common and bloody by the day. The followers of the old faith rally around the symbol of the Moon Queen, while Kemetics and Atenists use the Sun Disc of Amun-Ra and Aten as a symbol of their desire to burn away the darkness of the old eastern faith. African Solar worshipers flee the realm in droves, considering the fighting of followers of the moon and sun deities a grave heresy. The court has little concern for these clashes, instead concentrating on laying plans for defeating nearby realms, with the hope of creating a mighty Empire of the Sahara, from which the Garamantes can sweep and reclaim Egypt. The troubles have however now spread to your personal demesne, as one of your counties is experiencing a food shortage. What will you do?
Dismissal (Standard): The pheasants are hungry, you say? Then give the dumb birds some more seeds! (Gain unrest in county for five years, pay 5 gold for birdseed)
Dismissal (Kind or Generous trait): Redistribute my personal food supplies to the most needy. (Gain the "minor food shortage" health trait for a year)
Dismissal (Cruel or Zealous trait): Crucify anyone wearing the wrong symbol, and confiscate refugee property. Fewer mouths to feed. (2 year unrest, similar length of reduced income from county)
Event 7: Light In The Dark (Fires about a year after the last event, but for a Kemetic or Atenic Pharaoh only)
As you are riding around your demesne near your capital, you and your guards come across a village full of sick and dying people. After some interrogation, the surviving locals tell you to visit their water source nearby. Following the path, you come across the water source, one of the many underground canals, water trickling out of it at a speed and volume significantly lower than what you are used to. The water smells... rotten, even more rotten than the peasant who emerges from the canal, wielding a torch. "Thank the gods, a noble!" he exclaims, gesturing inwards, "I followed some strange outsiders here last night, and now it smells like death in here. Someone please follow me to find this lot!"
Dismissal A: You think I am stupid? You go in there yourself and bring whatever you find out here, in the sunlight. (Bad result)
Dismissal B: Guards, help him out. Find the source of this smell. (50% chance between bad result and good result)
Dismissal C: Fine, someone give me a torch. You two, come with us inside the tunnel. (80% chance of good result, 20% chance ruler dies)
Bad result:
No sound is heard from the canal for several hours. Then a mutilated hand floats out. You decide that for the sake of local safety, the village should be relocated and the hole bricked up.
Good result:
As your guards drag the mutilated corpses out of the canal, you notice they shine in bronze sun decorations. They are quickly identified as Aten Cultists. Statues of Aten with words like "We work in the dark to serve the light, we are Atenists, and this is the Atenist Creed." make it very obvious. However, as your guard points out, their heads are gone. A quick search of the village later, one of the persons dead from dysentery was discovered to have two of the heads in a box under his bed. A note was attached to it, speaking of a gathering of "Moon Lords."
