Originally constructed under the authority of the Earth Sphere Alliance, the exact location or even existence of the Thule base is almost exclusively a secret kept by high-ranking Union officers. Believed to be hidden below the northern edges of the Sermersuaq, the purpose of the installation remains unknown. It was one of the few bases totally untouched by renegade elements during the Guild War period, making further intelligence sketchy at best.
