In the mountainous region of Udurchukan, Far East Russia, there was a place unlike any other. The volcanic grounds were home to a variety of creatures, but one species stood out among the rest. The Olorotitans, also known as the giant swans of the mountain, majestic and beautiful Hadrosaurs that roamed these lands.

Their long necks were particularly elegant, giving them their name. These creatures were unlike any other, with their graceful movements and nature. However, life was not always easy for the Olorotitans, especially during their yearly journey through the volcanic field. Every year, 17 female Olorotitans risked their lives to lay their eggs in the warm, volcanic soil. They traveled in a thin line across a narrow path flanked by numerous vents of toxic gases. It was a treacherous journey, but the reward was worth it. The mothers carefully laid and buried their eggs in mounds, protecting them from the harsh environment. When the eggs hatched, the mothers greeted their newborn children and brought them some vegetation to eat. The juveniles were full of energy and playfulness, enjoying their new home in the volcanic fields. As the days of summer passed, the fields became covered in horsetails, providing constant food for the growing Olorotitans.
