Build Points are used across the Campaign Rules as a form of currency. However, BP is not money - nor does 1 BP relate directly to a given amount of money, so you can’t normally buy BPs with gold. Nor can you spend a fraction of a BP, you have to round it up to the nearest whole number.

1 BP might consist of a load of timber, the labour of a few dozen workers, a spell or two from the local cleric, The local Lord’s good will, food to feed your workers and something to pay them with. And workers are payed in land, rights, jobs and opportunity. But that all happens in the background.

For Example: If you build a Jetty– you source the wood and stone from somewhere, some rope, large bolts, nails, building tools etc. You have made work for quarrymen, a smith or two, wood cutters, rope makers etc. Then you need workers to actually build it.

Afterwards the workers might move out into the countryside (to some land the local lord has said you can use) and set up small holdings. A few more turn into fishermen - perhaps building themselves coracles or small boats or even just fishing from the Jetty. Their wives clean the fish, smoke them, make fish sauce and prepare them for sale in other way. Someone might set up as a fishmonger, while others hang around and find casual labour somewhere.

So really BP is ‘The Economy’ – and the number of BP you have represents the amount influence you have over the economy of your area.

Another time, 1 BP could represent the resources you need to build something completely different – and the knock-on effect you have to the economy.

Example 2 - Public Baths A group of settlers arrive and you tell them that they can stay if they help build a Public Bath. In return some of them are allowed to set up small holdings around your town (you have to get food from somewhere) and other build themselves small houses in the town itself. Some might finish up working in the baths, others become labourers or minor crafts people. 1 BP 'spent' and a public building gained.

Example 3 – Small Holdings and Road A group of settlers wants to live away from the town and you give then permission to settle down in an area, so long as they build a road through it. If it is a hilly area, you might have to subsidise them while they build - by diverting a BP (perhaps from taxation) into food and shelter for them while they get established.

Example 4 - Brothel A group of 'street girls' (and boys) move down from one of the big cities looking for a better life. The more attractive ones trade favours with the local youth to get a suitable building put up. You use your influence with the local Lord and other business men to get the right permissions - and soon you have a working brothel with a number of small houses locally for the staff. Part of the deal might be that the 'boys and girls' had to promise to do some extra work later, for the Local Lord.
