The Empire of Hetkaptah, with its capitol in Alexandria, Khemet / Egyptos, dominates the modern solar system. While their science has obviously moved on from the old Platonism, allowing them to establish colonies on multiple extraterrestrial bodies, but Greek philosophy is still an important part of their cultural heritage.
One way this manifests is in the emblems of the major branches of the military:
- The army operates over land, and uses the cube as its emblem, associated with the classical element of earth.
- The navy operates on and in water, and uses the icosahedron as its emblem, associated with the classical element of water.
- The air force operates in the air, and uses the octahedron as its emblem, associated with the classical element of air.
- The space force operates in outer space, and uses the dodecahedron as its emblem, associated with the classical element of cosmic quintessence.
But, that leaves one element and one regular polyhedron unused, which simply will not do!
So, what sort of branch of military service could be created with an association with fire, to use the tetrahedron as its emblem?
