A Sensor Fragment, formerly known as an Unknown Fragment, is a very rare Manufactured Material introduced in v2.3.
Originally known as an 'Unknown Fragment', this is a piece of a Thargoid sensor. Since they have not been given a designation by intergalactic trade authorities, it is impossible to buy or sell them legally.
