I have been building game worlds since some time in the 1980s, some organizations have appeared again and again - growing and developing in each iteration. Never let a good company die out, you might need it again later - and you can use all the old PCs and NPCs again - it saves inventing new things each time, is quicker and comes with history, personality and RP opportunity, bringing instant 'flavour'.

• FFTC - The Far Flung Trading Company specializes in those frontier areas of the world that other merchant houses aren't interested in, and started in the 1990s as a vehicle to support The Occidental Trading Company. Since then, it has grown to incorporate all the Merchant Shipping businesses that have been established in my games. Most were player based, although House Yitis was established by NPCs and became a favourite of mine. Most of the other shipping houses are just names to fill out the roster, although House A’Dair has featured before (in Porters Bar's history)
  • The Kassen Kompany - Formed by Gagak DeKassen (A PC that I played in another DMs game) and his party. They held land, ran businesses and had a small merchant house. The Merchant House is now run by NPCs, as part of the FFTC, while the rest of the holdings got 'distributed' when the game finished. One finished up in Gagak's possession, and still contribute to his family finances.
  • Occidental Trading The first PC based business in my game world, that served as a PC favourite for my original MK playing groups.
  • V&A Shipping
  • House Yitis
• -
• Church of Way - Originally The Brothers of the Way, now the Church of Way, this small church builds bothies and hostels for travellers. The original Way House was built by Yuthric Green-Teeth, and then grew into a widespread religious organization.
• The Amethyst Fist - an order of monks, who started off in a NWN world and have been developed for Pathfinder.
• The Raven College of Armes - Every game-world needs its honours and titles - The Raven College of Armes has done that since the very first world that I built. It was started by a PC (turned NPC) druid, as a cross between an early Celtic Druidic/Bardic college with the additional task of recording and verifying titles and coats of arms.
• The Golden Billet - A new organization that has only appeared in a couple of games, so far. It provides 'contracted out' protective services to states and organisations. A pure NPC organisation.
