In the Military Use of Gulmorvrin section we originally had an example of Sayorsaxe's calculations, but then decided not to show any numbers. I would be curious to see what numbers different GMs come up with.

Speaking as a GM, I would use whatever number makes the game work. The problem is that the Morgathians could have any number: 100, 1000, 10000. Whatever. Given that the Gulmorvrin have no need to sacrifice Aura to Klyss, the Church of the Unlamented Dead could stockpile them like cordwood.
Amorvrin are a very different story. Their need to sacrifice to Klyss means that there simply cannot be many of them, or the whole area would become uninhabitable for ordinary folks. A few homeless wretches disappearing every month is nothing in a town the size of Golotha, but if a hundred people are consumed by the Shadow every month, and it would become a (heh, heh) ghost town in a short time.
If there are 5 Amorvrin in all of Rethem, and they convert one human into a Gulmorvrin each month, and another 5 are created each month by the Church (botched rituals of Myrvria's Kiss, etc.) that is 10 per month, and thus 120 per year since, well, whenever. If since the end of the Balshan Jihad, the Church could easily defeat any army. Note that many of those could be from outside the Kingdom (slaves from Tharda, prisoners from Kanday, the Kuborans, etc.) imported for this very purpose. Slaves brought in for the Pamesani games who turn out not to have what it takes, prostitutes worn out in service, younger sons, the list goes on.
Can Ivashi be converted to the Shadow? Gulmorvrin Aklash adds new meaning to the Shadow!
What are the limits on controlling them? What are the limits on turning undead in this game? I must go read the invocations of Larani, and start recruiting from the Order of Belsirasin.
