Not necessarily intended for everyone. This is a highly structured variant of the challenge, as opposed to the main, freeflowing challenge.
==Agriculture==
Unlocked by building an Elder Dwelling in Dirt Hovel stage.
===Agricultural Nobility===
There must always be a Noble overseeing all of the Agricultural activity in any Settlement. As more extravagant classes of Nobility begin to move to the Settlement, the Agricultural Noble must always be of the highest class of Nobility possible. If the Agricultural Noble remains a Noble at the close of the Stone Hamlet Stage, he will be replaced by a Baron in the Iron Village stage.
Agriculture Nobles are bureaucrats, and have no other purpose besides shuffling papers around.
====Agricultural Council====
The Agricultural Council report directly to the Agricultural Noble. There must be one member of the Agricultural Council for every branch of Agriculture present in the Settlement. Members of the Agricultural Council remain 1 class below the Agricultural Noble--unless it is the Iron Village stage, in which case any Councillors who remain Elders must be replaced by Barons.
====Agriculture Advisor====
The Agriculture Advisor reports directly to you about all Agricultural concerns across the entire Empire. He is of the highest rank of Nobles that have moved to your Empire (Anywhere in your Empire).
====Capital Agricultural Council====
The Capital Agricultural Council reports to the Agriculture Advisor about the state of the various Agricultural activities in the Empire. There is one Councillor per type of active Agriculture in your Empire. They are responsible for all other Agricultural Councillors within their chosen field (no pun intended).
