When turns collide

Each target you attack holds one of your fronts, and Command research sets how many you can hold at once. The Warlord starts with fronts open before any research.

The Core's garrison, its emplacements, its wall and any allied army parked there defend it together. A siege turn then plays out in up to three steps.

1. 1Every attacker against the defender. Everyone besieging the Core that turn, allied or not, fights as one side. There is no half measure: if the defence holds, every attacker loses everything it sent, Marshals included.
2. 2The strongest besieger leads. If the defence breaks, the attacker with the most army left standing leads, decided without a fight. Only its Marshals spend: each one takes a point of the Core's Integrity, up to a limit per turn that Ordnance research raises. Every other besieger burns as many of its own Marshals as the leader spent, unless it is the leader's ally. A lone besieger simply leads.
3. 3Home with the loot, or a fight for the prize. While Integrity stays above zero, nobody fights anybody else: every attacker takes a share of the Colony's stockpile above what it keeps protected, as much as it can carry, and marches home. Only on the turn Integrity reaches zero do the attackers turn on each other, allies standing as one. The largest force of the last side standing takes the Colony, the losing rivals are destroyed where they stand, and the winner's allies march home. If nobody survives that clash, the Colony stays with its owner, its Integrity spent.

The defender loses the units that fell, any emplacements that fail to rebuild, most of its counter-spies, and, if Marshals were spent, that turn's monument level.

When Integrity reaches zero the whole Colony changes hands: the Core, every Holding, every building and the entire stockpile, food debt included. Every unit standing anywhere in it is destroyed, parked allies too, and the winner's survivors become the new garrison.

Every emplacement is destroyed and the wall drops a level. Work in progress is cancelled without a refund, a monument standing there is destroyed, and the counter-spies are gone. A captured capital becomes an ordinary Colony.

A raid meets a projection of the Core's emplacements, with the wall and the Armory behind them, plus any army standing on the Holding itself. The Core's own garrison stays home. Win or lose, a share of each side walks away: nobody is wiped out by a raid.

Raiders who win carry off the Holding's output for a stretch, as much as their surviving units can carry, and the Holding produces nothing until it recovers. They also take a share of the Colony's stockpile above its protected floor, which the Hideout raises. A raid never touches Integrity or the wall, but it can knock out emplacements.

Landmarks are fixed ancient sites that nobody can own as territory, only hold. Everyone can see who holds each one. An unheld landmark keeps a neutral guard that grows every turn it stands untaken.

Taking one is an attack at the turn like any other, and it holds a front. Attackers break the guard together, then settle it among themselves with allies standing as one, and the largest force left standing takes it. If nobody survives, nobody holds it, and the guard returns.

Your fighting units on the landmark are its garrison, and you hold it for as long as one of them remains. Send more to reinforce it and build emplacements there, but no wall. Allies can neither reinforce your landmark nor attack it. When someone takes it, their survivors become the garrison and every emplacement you built is destroyed.

Each landmark you hold makes every Colony produce more and build faster, and the bonuses stack. It is lost the moment the landmark is. Landmarks are also what you need to found a monument.
