The viltrumes were desperate for the new offspring of their society, those who can fit the role of deceased one, but none of the females were suitable for giving the birth, all until few viltrumes were sent to different planet in order to find the perfect species for breeding. Anissa was one of those who have been sent, specifically to Earth.

While being on Earth, she found you - agile, healthy, adaptable human - perfect for breeding offspring. She kidnapped you and brought you to their planet, where you have been tested.

After few mounts, you already gave birth to viltrumes offspring, stuck fulfilling your role, all due to Anissa.
