Fortification

Overview

The world of Empire is littered with walled settlements, fortresses, keeps, castles and fortified bridges. These lesser structures may be the target of a quest or skirmish but they are not important for the calculate of army strength present in a territory. Only mighty fortifications are tracked; sturdy castles, networks of carefully positioned forts; great stone walls with sentinel towers.

Fortification Strength

A campaign fortification is stationary and attached to a specific region. That region gains the fortification keyword. Fortifications have a strength, based on the same scale used for Imperial armies. A small campaign fortification has a strength of 3,000 - equivalent to fighting strength 3,000 raw recruits.

The strength of any fortifications in a territory are added to the strength of the armies present, but only for purposes of determining which side is victorious. Fortifications do not inflict or take casualties unless the orders issued by the generals for the campaign indicate that they are attacking the fortification or the region it defends.

For example, if the campaign is focused on capturing a forest region in Karsk then the presence of a fortification in a nearby region will be important for determining which side is winning, but will not directly affect casualties. If the orders for the campaign involve trying to assault the fortification, then it inflicts and takes casualties just like a campaign army.

Capturing and destroying a fortification

An enemy fortification is captured when it's strength is reduced to 1,000 or lower. A fortification that is reduced below 250 strength is destroyed, rather than captured.

Creating a fortification

The Imperial Senate can pass a motion to create a new campaign fortification. The cost to create a new fortification is 100 wains of white granite over the course of a year. The project requires a minimum of 25 wains of white granite for each season of construction until the full amount is paid. The campaign fortification is created after four successful seasons of construction.

Improving a fortification

The Imperial Senate can pass a motion to improve the quality of an existing fortification. Improving a fortification takes one year to complete. The fortification must be controlled by the Empire throughout.

• Increasing a fortification from a strength of 3000 to a strength of 6000 requires 120 wains of white granite.
• Increasing a fortification from a strength of 6000 to a strength of 9000 requires 140 wains of white granite.

Further increases in the strength of a campaign fortification follow the same cost increase structure.

Repairing a fortification

An Imperial fortification that has been damaged regains one tenth of it's maximum strength every season provided the territory is under Imperial control. Additional repairs can be effected by a motion in the Imperial senate and the expenditure of wains of either white granite or weirwood.

Natural repair

If an Imperial fortification is located in an Imperial controlled territory and is not subject to an attack during that season then it automatically recovers 300 strength. Imperial fortifications in territories controlled by barbarians or which are attacked during a season are not automatically repaired.

Emergency repair

The Imperial Senate may pass a motion to authorize the purchase of additional materials - in the form or either white granite or weirwood - to speed up the repair of an Imperial fortification. This represents a concerted effort by the Empire to repair the fortificaiton. Emergency repair, like natural repair, takes a season to complete.

In a single season, the first 30 wains of white granite or weirwood restore 20 strength for each wain allocated. The next 30 wains provide an additional 15 strength each. The next 30 wains provide an additional 10 strength - and so on. The rate of emergency resupply resets each season so the white granite and weirwood spent in a subsequent season is not affected by earlier actions.

Repair costs might be 25 white granite or weirwood for an extra tenth of maximum strength, 75 white granite or weirwood for another increment, and 150 white granite or weirwood for a third increment in a single season.
