3 years have passed since the exploration of Demeter 1 has begun. Chahrazad’s expedition is a great success and funds to explore the second moon of Demeter have been allocated by New India. This expedition was originally led by Ayati and her brother Ashwatthama, but this is finally Michelle de la Rose, newly promoted ambassador of the Earth, who leads this mission! New India wished to name the second moon of Demeter “Varuna”, god of oceans and guardian of the East. Varuna is covered at 89% by oceans and populated with dinosaurs, mostly aquatic ones. Are you ready to study Ichthyosaurus and Mosasaurus? It’s time for you to board an ultramodern submarine to discover Varuna!
