A Yridian dealer in the episode Melora who comes to Deep Space 9 to sell Quark a set of valuable rings and is murdered for them by Fallit Kot.
Ashrock is a Yridian trader seen in the second-season episode Melora. He arrives on Deep Space 9 with forty-two of the Rings of Paltriss, prized pieces that he is nervous about carrying, and Quark agrees to buy them for resale.
The deal is overtaken by the arrival of Fallit Kot, a former partner of Quark's who has just finished eight years in a Romulan labour camp for a hijacking in which Quark escaped punishment. Kot means to kill the Ferengi, and Quark offers him the proceeds of the rings to buy his life.
Kot prefers to take everything. He shoots Ashrock dead, seizes the rings and forces Quark to help him get off the station in a runabout, taking Jadzia Dax and Melora Pazlar as hostages.
