Silurian nest (Retrieval)

A Silurian nest was located in Greece.

Kate Stewart and Petronella Osgood went there to find a control device for Krelix's sea creatures. It was a research facility where the Silurians kept information on their biological make-up and their venom. Tryska blew it up to stop UNIT from gaining more of their secrets. (AUDIO: Retrieval)
