After destroying the human farm, Lieutenant General Nova Revel brought the surviving children with him and flew towards the coordinates his wife had sent to him. The rescue shuttles were found in that place where Alula Celeste and the rest had secured their escape route.
At first, the survivors almost ran away when they saw the Fifth Prince of the Zerg race. Only when they saw him release his quantum beast merge skill did they believe that he is indeed human. The former marshal even cut his palms to show that his blood is red.
[Note: Zergs are bugs so most of their blood is green.]
