Sbrithnir's Crew
Structure
Like all crews, Sbrithnir's Crew was made up of a number of Writhes and gangs. In terms of how the crew functioned, it is the organisation of the gangs that we look at here,
Around half the Crew were full members of a gang: the remainder - the "Unganged" predominantly the young, the infirm or those whose abilities best fitted them to unskilled labour, normally in support of the Burrowkiss. There were also around a dozen unganged who were specialists and crafters outside the gang system. Sbrithnir's Crew were unusual in having unganged adults and, perhaps in consequence, were more formal in their use of gang ranks as titles.
Ranks of the Ganged
The gang members rank was a title or honorific - the leader, for example of the Clutchkiss would be formally addressed as The Clutchken when referring to the role, Preparlon Clutchken as an individual within the crew and Preparlon Ken within the crew. An unganged drakiss might be referred to as, for example, "Fivuni Unganged" - an address that would in many crews be a mortal insult but with the unganged specialists vital to parts of the Crews economy, the term was far more nuanced in Sbrithnir's Crew.
The Crew's organisation prior to the Union with Jorrath, the crew numbering 209 at this point.
Assets
The tunnels and halls taken from the Monkin-doo and expanded and decorated in their own style; the metalwork captured and hoarded from those wars and their own mining and manufactures not sold in trade. Though not poor the hoards of the Crew and Sbrithnir were rarely large for they traded more than many and ravaged less than most.
They also maintained an extensive archive of historical detail on both Sbrithnir's life and the wider history of Senteru since their arrival. These have been well used by the Tarembura in support of their oral tradition. This in turn has strongly influenced the crew's culture and the development of their literary tradition, most notably in "The Lay of Jorrath and Sbrithnir".
Economic Basis
Unlike most Crew's Sbrithnir's Crew have never engaged in agriculture or foraging to a significant extent (at least after settling at the Roost). Food is mainly obtained by trade with the Monkin-ban (metalwork and protection from the Monkin-doo being the prime goods of exchange), though since the late fourth century the Alkiss have engaged in the cultivation of mushrooms using wood debris. Gifts from the Tarembura in return for access to the Crew's archives have been a significant source of grain.

I see a lot that I want to explore here! A word of caution in regards to the challenge -- there's a lot of information here that clearly depends upon a knowledge of the world that many people (likely the judges) won't have. I don't know how much leeway you have with word count, but you might want to explain some of this a bit more in the article itself. Just a thought.
