Jacob was startled when he saw those novel creatures riding on a whale-like ocean beast were coming in his way. This was his first witnessing this scene, and even from here, he could tell that the ocean beast was at the peak of its unique rank.
'Don't tell me they are from the ocean races?' He speculated.
Autarch had already told me about ocean races because Masha also belonged to an ocean race, but she was a runaway because she was experimenting on her own race members.
Furthermore, the ocean races were very mysterious, and most of the natives of the Unique Plains were unaware of their existence because they rarely left the ocean and came to the surface.
Jacob has no idea that he had unknowingly trespassed into the territory of ocean races while fleeing from the swarm of Ice Fiend Locusts.
