. As outside threats eventually dissipated, Emperor Shunaiman applied his efforts to strengthen his empire internally. In the ten years that followed, the new empire became strong, controlling the entire continent through large-scale development and territorial expansion. Castles were built and lords appointed, taxes collected and the empire economy steadily grew. Around this time, some proclaimed the faith of Shilen among the populace. The Emperor ordered his lords to punish them, but they were unable to drive these zealots from the kingdom. Though many died, the Emperor would not relent. Following Anakim's gnosis of the gods, the emperor mobilized the Nephilim and discovered the six underground temples of the worshippers of Shilen.

Shunaiman called these underground temples the Catacombs, for they were the final resting places of those cult members who rejected the worship of Einhasad. Shunaiman's military attacked the gangs of Shilen who had already faced defeat at the hands of the Nephilim. However, ultimate victory was not an easy task to obtain. New enemies appeared, called the Lilim. The Lilim were created from the dark magic of Shilen, and they were unaffected by the Nephilim. As they were unafraid of death, these warriors knew not how to retreat on the battlefield.

After an extended and all-consuming battle, the emperor finally subdued the six Catacombs, but his forces were decimated in the process. Countless corpses of the Lilim and Nephilim were scattered about the underground temples. Certain there were no other forces to challenge his authority, Shunaiman cast a Seal of Gnosis on all the Catacombs. This first of the seven seals was so-named because it was a miracle achieved through Anakim's gnosis. Entombed in the deep underground, the groups of immortals that followed Shilen began to disappear from memory .
