Polysatyr

Polysatyrs were a micro light beam that could be contained in a jar. Around 0 ABY, during the one night a year gifts were offered to the Queen of the planet Ktath'atn in exchange for favors from her, a Dressellian offered a microflora effusion of polysatyrs to the queen. The Dressellian then added they had brought magnifying equipment to show, but was interrupted by the queen's servant Varroa, who remarked the equipment would not be necessary and that the queen would consider the contribution. Shortly after, the queen asked all the guests to leave, including the Dressellian with the polysatyrs, after she witnessed the Jedi-in-training Luke Skywalker use the Force against an Ezaraa warrior.
