An enormous, crimson-colored fleet of spaceships reached the planet of Amphibi at time record, in just a few days of interstellar travel, the entire fleet of spaceships arrived within the territory of Jakob's young sibling, Valen. Although both siblings were in the same Great God-Realm, and their difference in power was not that big, their ranks and prestige in the Vampire family were very big. Jakob was someone above his brother, and through what he was taught by his mother, father, and uncle, he had to be ruthless even against his siblings.
