Aside from the Government, there are lesser powers that play a role in society. Organizations such as the Congregation of Merchants and the Nauts hold an inordinate power over coin in the country. The Order of the White Oak exist for the government yet outside their purview and the Night Guild is a constant reminder that crime is always existent in some way, shape, or form.
The Congregation of Merchants serve as a collection of the various merchant guilds and tradesmen under a collection of wealthy Merchant Princes. Through various alliances among tradesmen and guilds, they present a loose confederacy of solutions to the economic troubles of the connected mainland.
The Nauts are an organization of sailors, privateers, and (in some more shadowy cases) as pirates. While the Nobility have their own private vessels (both in sea and in their legendary airships), the Nauts control the sea with their unusual source of nature magic. The inner seas region of Halruaal can be extremely dangerous if a vessel leaves established trade routes and very few seaward excursions succeed without the Nauts' help.
The Order of the White Oak are akin to an officially recognized paramilitary. They guard against the most dangerous supernatural threats that Halruaal has spawned and jail extremely dangerous mages in the Magical Prison of Aenor.
And underneath all of these organizations lurk a shadowy collective known as the Night Guild. Whether it is information, thievery, or assassination, few but the Noble House of Clan Oni compare with their skill. They have a hand - or at least an ear - in every aspect of Halruaal.
