The Masari (Second Human Empire: ?) are the oldest and most mysterious in the Yuii'iooi universe. The Masari are an ancient and advanced race that, millennia ago, became the saviors (some say creators) of the original Hierarchy race when they gave them the technology needed to survive. However, the alien creatures did not return the kindness shown to them and the Masari were all but wiped out, save a group that went into hiding on Earth. There, they began instructing mankind and, in the process, inspired many ancient mythologies, until they went into stasis as their city-ship, Atlatea, sank under the waves. The Masari joined the Coalition of Independent States to survive the war against their rivals.
