教義

各宗派には多くの教義（doctrines）があります。教義は宗派の中で何が許され、何が禁止されるかを決定します。

主要な教義

主要な教義（main doctrines）は宗派そのものの規則（rules）を決定し、領国（realm）がどのように統治されるかに大きな影響を与えます。

カテゴリー	教義	説明文
性に関する見解	男性優位	男性はより強く、この過酷で容赦のない世界で私たちを導くことができるので、我々は彼らに社会の統治を託す。
	平等	性別などと言う理由によって、優れた人へ政府的役割を与えることを拒むのは馬鹿げている。 我々の社会を治める能力を持つものには何をも許可せねばならない。
	女性優位	女性は、自分たちだけが我々の社会を上手く統治するのに必要な知恵と思慮分別とを持っているということを幾度となく証明してきた。
宗教的態度	Fundamentalist	我々の信仰は唯一にして真の信仰であり、我々の言葉は唯一にして真の言葉だ。[ReligiousText]からの逸脱は全くの冒涜である。
	正義	人である我々は、[HighGod]の意志を完全に理解することはできないが、それでも我々の司祭は、何が神聖で何が不敬であるかについて、そこそこ良い考えを持っている。
	多元主義	神の意志について正しい解釈が一つしかなく、他のすべての見解が間違っていると言うのは全く愚かなことだ。私たちは[HighGod]を崇拝する独自の方法をそれぞれが持っている。
聖職者の伝統	神権制	認められた司祭だけが、我々の信仰の教義を守り、さらには、我々にとって神聖な場を管理監督することを委ねられている。
	在家信者	忠実な信者は我々の信仰の教義について十二分に理解し、従い、説くことができる。
宗教指導者	なし	一人の人間が[HighGod]の御心を真に理解するに能うと考えるのは全くもって愚かなことである。我々は己の心に従って、あの方がお考えであるか悟らねばならない
	神秘的	物質世界と霊的な世界は似通っていない。我々は、霊的な世界が独自の指導者を持ち、その人物が我々を導き我々の信仰が肉体的な欲情によって冒涜されることを防ぐことを確かなものとしなくてはならない。
	世俗的	精神的なものと肉体的なものは本質的に結びついており不可分である。一つの領土に二人の異なる指導者がいるのは愚かなことだ。
ムハンマドの継承	スンナ派	アブー・バクルはウンマによって政治・宗教双方における正当な指導者に指名された。
	シーア派	アリーはウンマの指導者としてムハンマドから指名され、彼を介してのみ宗教的指導者の系譜を辿ることができる。
	ムハッキマ	アリーはムハンマドの正当な後継者だったが、彼は第一次内乱で人間による調停を受け入れた、これはアッラーの意思に反する！アッラーだけが私たちに相応しい指導者をもたらすことができる。
	ザンダカ主義	私たちは預言者の系譜を正確に辿っているのかもしれないが、他のイスラム教徒からは背教者だと目をつけられている。罪人達には私たちをザンダカ主義と呼ばせればいい、私たちは真実を知っているのだから！
世界教会主義	世界教会主義	私たちの宗教指導者たちは歴史的に、さまざまなキリスト教宗派間の協力を強化するために、信仰間の対話に従事してきました。

Attempting to form such a bond with multiple people at once is sacrilege.

	Always Allowed	Characters can spend  100 piety to divorce	300 if Disallowed 200 if Must be Approved 100 if Always Allowed	Marriage is merely a partnership between two people, and like all partnerships, can be ended at will.

	Unrestricted Marriage	Characters can marry all family members	1200 if Close-kin Taboo 900 if Cousin Marriage 600 if Avunculate Marriage 300 if Unrestricted Marriage	It is natural and healthy for family members to love each other, and those who say that love should be restricted to non-sexual relationships are fools.

Crime doctrines

Crime doctrines determine whether certain acts are accepted, shunned or  crimes. Shunned activity gives rise to secrets that can be blackmailed for a  weak hook, while criminal activity gives rise to secrets that can be blackmailed for a  strong hook. Exposing such a secret gives the relevant characters a negative fame trait, and causes them to lose a level of  devotion and  opinion with all characters who consider the activity shunned or criminal.
