To prepare for the annual war, Crown Prince Barbro suggested that the Royal Army conscript the adventurers, especially the adamantite adventurer group, Darkness. Baron Cheneko supported the idea wholeheartedly. Due to his enthusiasm, King Ramposa III gave him the mission of recruiting Darkness to the Kingdom's cause. Cheneko failed in his mission, as Nabe rebuffed him stating Momon was on a solo mission.
During the Sorcerer King's procession into the newly conquered city of E-Rantel, Momon defended a young boy and his mother before the cortège. While Albedo was prepared to execute the upstart, the Sorcerer King, impressed at the hero's defiance, relayed orders to Albedo and coerced the adamantite adventurer into servitude lest there would be a massacre of the remaining humans within the city. Outnumbered and seeing no alternative, Momon accepted the term, swearing Darkness to become subordinate to the Sorcerer King and responsible for killing any rebels. It was thanks to this that the inhabitants of E-Rantel remained passive under their new monstrous king, refusing to rebel, lest they tarnish Momon's reputation.
The adamantite adventurer group, Darkness was said to be the most powerful and strongest adventurer party out of the three groups in the Re-Estize Kingdom. This was evident enough for other adventurers to see in Momon as someone, who has reach the pinnacle of what truly defines adamantite to be. With only a warrior and a magic caster, it is thought to be next to impossible to resolve the many dangerous incidents that they are capable of resolving. Even Evileye herself closely estimated that Momon's and Nabe's strength are the work of inhuman feats, believing them to be God-kins, who has the blood of a player. Out of all the warriors Evileye has came across in her lifetime, she concluded that he is the strongest warrior by far.
