There are somewhere between 100-200 people attending the auction. And many of those are accompanied by staffs and retuines large and small. In addition there is a large Administratum staff overseeing things, Imperial Guard guards (pun), as well as the members of the Mourner's Guild (the staff that acutally runs the islands and its facilities - a robed bunch that can be described as a cross between tech-adepts, preachers and accountants).

I cannot hope to describe this multitude of people in any great detail, but I hope you get a glimpse of the colorful cacophany of people that are now housed within the labyrinthine halls of the House of Dust and Ash.

Some of the more prominent attendees include:

Captain Rubio of the "Ozmandius": A very vocal and visally flamboyant Rogue Trader. Seem more interrested in just being present at the event, rather than actually spending his gelt on auctioned items.

Magyar Marshrek: A low-key figure that has more gelt than you would expect. He has a very small staff (only 2 bodyguards). He seems more of an adventurer or explorer than anything else.

Master Sunoench: A ranking Solomon Guildmaster. He's representing a large conglomerate of corporate interests. He has a big staff and money to spend.

Some other characters:

Locutor Mayweather: Minor Administratum adept. Inquisitor Marr's inside man. He's you're contact here - if you want to use him that is.

Greel, the Head Mourner: A very tall dark-robed figure. Leader of the Sorrowful Guild (aka the Mourners). Seen lurking about from time to time, or speaking with the Adminitratum staff.

Provost Hiram Bland: The leader of the Administratum contingent. Empowered by the High Lords of Terra (through the Chancellery Court) to dispose of the estate of Erasmus Haarlock.
