After being surprised, the Elf Queen explained to Ciel about them.
The first was the leader of the four Death Gods, one of them was the Eastern Death God who was the mother of Elliot Lambert. The god that the Ice Goddess fought against at the Pole of Hell was also one of them, called the Northern Death God.
As for the second one, he was actually the Patriarch of the Lambert Clan.
Both were powerful in their own ways.
However, the Old Geezer, the Elf Queen told Ciel that the old man was the strongest under the Ancient Night King. He was so powerful that even other Supreme Gods would prefer to avoid him.
"Will you be able to drive them away?" the Elf Queen asked Ciel, still in shock that Ciel could control this domain.
Ciel nodded with a faint smile in response.
"What about killing them, is there some kind of method to attack?" Ciel's response apparently made the Elf Queen inquire further.
