The mysterious Gree starship known as Gray Secant carries a long and unclear history. According to the Gree, this fully-automated vessel was launched by their ancestors at some point in the distant past, though conventional sensor technology has been unable to determine the ship's precise age or even its composition. As a result, there is no way to know the ancient starship's capabilities for certain, though most experts believe its technological sophistication to be well beyond contemporary Republic and Imperial science.
Among the Gree themselves, Gray Secant carries an almost religious significance. The ship was sent out from the Gree Enclave to explore and analyze the rest of the galaxy over the course of many millennia; getting to see one of their ancient legends at work firsthand is understandably exciting for the Gree.
