S03:É22 - S03:E22 - Heart of the Storm

In the final chapter of Lost World, the plateau itself is threatened. A rift in time and space collides with the explorers, as Finn and Veronica are briefly transported into a post-apocalyptic future while Roxton out runs 17th-century Conquistadors and Marguerite is captured by Druids as a human sacrifice. An ominous storm approaches the plateau and threatens all its inhabitants, and Veronica realizes that she must become its Protector. In attempting to fulfill her destiny, she taps into the power of her mother's pendant--the Trion, but her sacrifice could potentially destroy the plateau rather than save it.
