Dawn leadership
The Dawn territories are dominated by the powerful noble houses. The houses manage their great estates and raise soldiers to fight for the Empire. Houses are lead by an Earl who is selected from among the members of that house. Earls usually dedicate themselves to the advancement of their noble house. The accomplishments of a House reflect directly on its Earl, an acknowledgement of the role that the Earl plays in ensuring that every member of the house is given the support they need to triumph.
The means whereby an Earl is selected vary from house to house, and while it is reasonably common for an Earl to have some hand in selecting their successor, there is no concept that they "appoint" their heir. Membership of a house is achieved by passing the house's Test of Mettle, although a degree of status is often assumed by those sons and daughters who have been raised in a house (who are technically yeoman).
Each house sets its own test and only the behaviour of those who have passed the test reflects on the house. As a result a house must keep the tests difficult to maintain its reputation. Those houses that make the tests too easy face the very real risk of having no children placed with them by other nobles - no Dawn parent would want to place their child with a house that is tarnished by mediocrity.
While it is theoretically possible for a yeoman to achieve high office, in practice only nobles become Senators or Generals. A yeoman who somehow managed to achieve a position of authority without noticable miserable failure would almost certainly be approached by Dawnish noble houses keen to attract a rising star whose glory would reflect well on them.
By contrast, it is largelly considered demeaning form nobles to involve themselves in the business of the Bourse. Money is something that nobles simply should not be worrying about. A noble who spent too much time in the Bourse might cause others to question her commitment to glory and to the furtherance of her house's goals.
The Synod and the Conclave, by contrast, are open to both yeoman and noble alike, although again a yeoman who rose to prominence in one of these structures would likely attract a great deal of attention from the Dawnish nobility.
It is not unknown for a yeoman to refuse the offer of a Test of Mettle, although it is extremely rare. On a very few occasions, where the glorious nature of the yeoman is clear to all, such an individual may be declared to be the founder of their own noble house - although this is exceptionally rare and requires the support of a large number of Earls. If a yeoman refuses this unique honour, it is usually taken a sign that they would be happier elsewhere, probably in the Marches. While it is rare for the people of Dawn to exile a yeoman, it is not unknown, but usually only when the individual has proved to be so uniquely un-Dawnish that even the Egregore will not turn a blind eye any longer..
Each territory in Dawn sends a single senator as represenatite to the Seante. To choose their senators, the houses compete in a grand tourney. There is one contest for each territory, and no requirement that the candidate live in the territory for which a senator is available. A house may enter any number of contests, but an individual noble may only contest one seat. As a result smaller houses tend to concentrate their strength on a single seat, whilst the most powerful may split their members between two or more. Politics plays a role in the tourney of course, but at the end of the day this is Dawn – one cannot achieve glory by getting other people to stand aside and let one pass.
In theory an Earl of a victorious house could take the seat themselves, but most choose not to, preferring to leave the business of the Senate to those trained to it. The Senate offers opportunities for much glory, but they are difficult to achieve without special training. Those that possess this training are called Legislators. Professional politicians these nobles study oratory and debate as well as the history of the Senate. These dedicated politicians have helped Dawn hold its own in the Senate.
Also, in theory, an Earl might present a yeoman as a candidate for a Senatorial seat, but on the rare occasions this is attempted the yeoman is usually found out and tends to be ganged-up on by the other candidates under an unofficial truce until the field is clear of unworthy candidates. An Earl that attempted this would bring great shame on their house.
