After the destruction of the capital of the planet Grandmist, Darian ordered everyone in his army to move and support the other planets.
Even though a universe is something immense in theory, the Universe of Heaven's Will only had 321 planets with Spiritual Guardians. There were a few dozen planets with plants and very primitive life forms, but since the whole universe was scarce in life and had no natural power at all, it wasn't worth populating or going to those places for anything.
The only places that truly mattered to the Spiritual Guardians were their native planets, because that's where they built inscriptions with countless resources, turning them into places with power.
In other words, the job of Darian's army was much simpler. They just had to attack the nearly two hundred planets allied with the enemies and completely dominate them.
