Learning that Hans lies somewhere further east across the continent, Kate discovers that the only way to reach him is via a specially designed clockwork locomotive, built by Anna at her brother's request, and manning it with special animatronic man named Oscar. Before leaving, Kate is tasked with retrieving items important to Hans, that Oscar requires before he can allow them to depart the mammoth doll and two clockwork music boxes. Acquiring all of them, the pair eventually begin their journey eastwards, stopping at Barrockstadt, a failing university. While Kate seeks a means for them to continue, she explores the establishment and soon learns more about Han's interests in a mysterious tribe of people known as the Youkol, who lived with and domesticated mammoths that reside on the titular island of Syberia (inspired by the real-life location of Wrangel Island in Siberia, the last place on earth where mammoths survived).
