>>106632473Morijigoku's military strategy relies on a few principal components.
First, Unity Against Invaders. While the provinces of the country are at times highly antagonistic towards each other, even escalating to civil wars at times, they reliably agree on truces when an outside forces attempts to exploit those weakness, in no small part thanks to the heavy hand of the religious class which tends to remain neutral in inter-deadbeat conflicts.
Second, the country's littoral navy. The richest and most populous cities of Morijigoku are found on its coasts, alongside the Bay of Skull, and these have many private organizations heavily invested in securing the passage of trading vessels through the body of water and the part of the intercontinental channel it joins up with. Thus, many magical pykrete cruisers patrol the region, provide escort and essentially bulk up the country's defensive navy.
Third, to the south, the Bone-Dry desert which extends into /vspo/ provides a natural defensive buffer zone that is difficult to traverse and supply an army on, making attacking the country from that direction difficult.
Should an invading army pierce deeper into the land of the Dead, the final piece of the national strategy would come into play, in the existence of the Illium Valley. Found high up in the Onyx mountain, the region is very densely populated, well fortified against invaders attempting to climb up the mountains, and the whole region is under the effect of a magical cryogeny which lowers the temperatures to an Arctic frost year-round. These highly defensible and politically-aligned regions would be where the leadership of the country would retreat to, to produce supplementary magical equipment and weaponry and prepare a counter-strike against the invaders. This is a scenario that has played out a few times over the course of Morijigoku's history.
