We can keep them constantly unhappy, then when faced with a massive siege, we execute the relatives to push them over the edge. We could hold parents hpstsge for this purpose. Then, we unleash the dwarf on our enemies
This is actually a really good idea.
That idea is the dwarven equivalent of a nuclear reactor -- keep the core on the verge of a chain reaction but never actually let it get there.
And just like real-life nuclear reactors, something going wrong results in flying limbs and major infrastructure damage.
But we can control when the
cadmium rods dear relatives are executed, for the most part. Keep them in a locked room with some quick way to kill them, and as long as the food and drink supplies are brought in, they should be fine. Even if something holds up the alimentary delivery system, it takes a while for dwarves to completely starve.
I think.
