The Untamed Wilds
The strength of a realm is measured not only by the power of its rulers and armies, but also by its economic health. Many regents have ruined their lands through careless fiscal policies. Each domain turn, a regent must cover the expenses of his government. The most common seasonal expenses are military payroll, domain maintenance costs, court costs, vassalage agreements and tribute. These expenses are paid from the domain’s treasury.
The only normal source of regular domain regency expense is through a vassalage agreement bound by a ceremony of investiture. The nature of the investiture realm spell causes this transfer of regency to occur automatically. Domain events are another source of RP gain or lose. At the end of each domain round, scions may gain or lose regency based upon their actions in the domain event as stated with the events.
If a regent is unable to meet the RP expenses, the treasury is automatically reduced in order to pay the necessary RP; by 1 GB for each missing RP. Note that this expense occurs immediately after collection or in case of events; the domain round. This means being a vassal has a real cost, because this timing makes it impossible to “give away” regency points that you wouldn’t be able to collect yourself. Likewise it has a real advantage to your liege lord, as long as their current RP reserve is not at maximum. A standard vassalage agreement generally requires the vassal to provide 1 RP per province or holding held; but such agreements can vary significantly.
If the treasury is also insufficient then the regent must take a loan. For each GB missing he or she must skip one domain turn to repay the loan. No domain actions can be taken during this time, although the normal defenses against hostile actions still apply. If the regency loss was due to a domain event the character may use the regent domain action event handling as described in the domain events (see domain action round) to try to remedy the event, suffering the consequences on failed attempts normally and stacking those penalties against those already received.
Domain asset maintenance costs
The administrative costs of province, holdings, trade routes, and other income generating domain assets are already factored into their collected net income. The cost of non-income generating assets, however, must be paid explicitly. These constructions may generate some revenue, but their regular revenue is insufficient to cover the expenses associated with payroll and/or routine maintenance.
All military units have a seasonal maintenance cost. Active army units have a seasonal maintenance cost of 1/5 their muster cost. The cost per unit is given in the table in Military units. Active naval vessels have a maintenance cost of 1/10 their build cost.
