Afterward... it conducted a sacrifice ritual, offering the last ember of its own world entirely to the Shadow Lord.
As the last member of its civilization, the last cherished descendant of the great world's will-owned race,
it offered the entire Main World to the Shadow Lord as well.
For such an offering that was served up on a silver platter,
the Shadow Lord rarely responded.
It transformed the Main World, where the Shadow Three-headed Dog resided, into a Shadow World and pulled it into itself.
The Shadow Three-headed Dog, in turn, became an Abyss noble.
It became a follower of a follower of one of the Shadow Lord's followers...
The world and civilization of the Shadow Three-headed Dog were also destroyed.
As for the last spark it left for its civilization, because of the Main World's shadowization,
the connecting passageways were severed, so there was no need to worry about the Abyss tracing the origin and pursuing destruction.
