IFAQ: The Houses At War

Today I want to continue the discussion of the Dragonmarked Houses with a few questions raised by my Patreon supporters. The first comes from Joseph:
My understanding is both Lyrandar and Orien participated in the supply lines of the nation's militaries, not just civilian supplies. Was their neutrality respected? Was that part of the price? Or did attacks happen, probably while trying to disguise the source?
To begin with, it's important to consider the nature of the Last War. It was never a total war, fought with the intent to utterly annihilate the enemy. The goal of every nation was to place their ruler upon the throne of a reunited Galifar... which in turn meant that severe destruction of infrastructure and attacks on civilians were discouraged, because ultimately you're hoping that all of it will be YOUR infrastructure and that those civilians will accept your leader's right to rule. So to begin with, just consider our rules of war. We can be sure that the Five Nations were operating under similar restrictions, if not necessarily identical: Targeting civilians was a war crime, and civilians, aid workers, and medical personnel should be protected. In the early days of the war, the Twelve established a basic set of principles with the leaders of the Five Nations. Essentially, house forces were to be treated as noncombatants, even if on the battlefield... and in turn, would not be expected to engage in combat. A Cannith artificer might be present with a unit of soldiers to maintain the warforged and artillery, but they wouldn't engage in active combat and offer no resistance to an enemy. A Jorasco healer would only heal soldiers of the nation that contracted their services, but again, they wouldn't fight members of an opposing nation. This would in turn apply to their vehicles as well. The lightning rail and Orien carriages were forbidden targets. If a coach was transporting military personnel or supplies, it could be STOPPED and those supplies could be confiscated or personnel taken prisoner, but the coach and its Orien crew should be allowed to pass.
That's the basic principle, and it further increased the value of those services; a purely Karrnathi coach is a valid target for Cyran attack, while an Orien coach is inviolate. Of course, this is the PRINCIPLE, but there's a number of additional factors.
- There were always commanders and soldiers willing to disregard the rules of war (just consider the destruction of the White Arch Bridge or the bombardment of Korth). Just because you weren't supposed to target the lightning rail doesn't mean it didn't happen.
- Any House personnel or vehicles actively engaging in conflict forego this protection. So first of all, Deneith mercenaries are treated like any other combatant. A Orien coach that's got a mounted weapon and fires on soldiers can be destroyed. And if the Cannith artificer disobeys House orders and fights alongside the unit they're embedded with, they become a valid target. Certainly, there were times when soldiers would claim House personnel offered resistance even when they hadn't.
With both of these things in mind, bear in mind that the primary incentive against this behavior was financial. House personnel serving with the enemy were not to be killed, but they would be taken prisoner and ransomed back to the house. There was a clearly established rate of exchange and this would be applied against that nation's bills with the house. Meanwhile, the houses would impose financial penalties and raise rates when nations violated their rules. So As a soldier, if you kill a Jorasco healer, you're costing your nation gold—while if you take them prisoner, you're saving money. It's not simply a good idea; officers would enforce this seriously.
So in short: people generally respected the neutrality of the Dragonmarked houses. It was rare that they would, for example, blow up an Orien caravan even if it was carrying military supplies. However, they could STOP the caravan and confiscate those supplies. Or they COULD blow it up, likely trying to pin the crime on another nation. But if it was the truth was discovered, they would suffer financial penalties. So you can be sure it happened, just not constantly.
A secondary point to consider here is the fact that the houses wield monopolistic power unrivaled by any corporation in our world (because we have laws preventing it!). For many of the services they provided, there simply was no reliable alternative. Nations certainly worked at it: the Arcane Congress surely worked to develop a system of arcane communication that could take the place of the Sivis speaking stones, Thrane assembled a corps of adept healers, etc. But none of these had the full scope of the services the houses could provide. You couldn't just buy your warforged from somewhere else, and if you didn't work with Orien your goods would take longer to reach their destination. Every nation relied on the services of at least SOME of the houses. There was undoubtedly at least one incident where an officer seized control of house facilities, essentially seeking to nationalize them—or even just used a house facility as a shield for military operations. This is where the Twelve was vitally important, because while ONE house might have trouble challenging a nation, no nation could make do without the services of all twelve. So an attack on a Vadalis facility could result in a rate increase from all houses—or even a service blackout for a particular region. Again, these things surely happened—and there were consequences when they did.
Deneith seems like it would have substantially higher casualties than the other houses due to its focus. Do they ransom their heirs if they're captured during house business? Do they do anything special to keep their numbers up?
As noted above, Deneith personnel serving as soldiers are valid targets and don't receive the same protections as a Sivis stonespeaker or a Jorasco healer. With that said, the general rules of war likely prohibited killing soldiers who are too injured to fight or who surrender (again, that doesn't mean it didn't HAPPEN, just that people were supposed to accept surrender). So Deneith soldiers would have to fight fiercely enough that people would actually want to hire them: but they could surrender if seriously injured. And just as with all house personnel, there was surely a system of ransom for them. The rate would vary based on the position of the person: a marked Deneith heir would bring in a good ransom, while a mercenary with no blood tie to the house would command a fairly low rate. But soldiers would know that if you could take a Deneith officer alive, it's best to do so.
Having said that, it's also important to remember that the bulk of Deneith soldiers aren't blood heirs of the house: they are mercenaries licensed and trained by the house. In some cases—look to the Ghaal'dar and the Valenar—they weren't even trained by the house; the house simply served as a broker for their services. So losing a Blademark unit is a loss to the house because they'll have to recruit and train new soldiers—but they'd only lose a few blood heirs in the process. So they certainly had higher casualty rates than the other houses, but not every slain mercenary was a Deneith heir.
