Syp, a type of woody flora, originated from the marshy, high-gravity environment of the planet Ossel II. Highly valued due to its robust nature, syp wood represented the primary and practically sole tradable commodity of Ossel II, beyond its indigenous inhabitants, the Ossan people. Merchants journeying to Ossel II with the aim of procuring syp discovered that acquisition was contingent upon the acceptance of an Ossan individual into their crew. This condition constituted the sole trading arrangement deemed satisfactory by the Ossan.
