Ashrock was a Yridian trader with his own vessel who visited Deep Space 9 in 2370.
He was interested in purchasing a satchel of the Rings of Paltriss from Quark, who found himself in possession of forty-two of the rings. Warned of Quark's hard-bargaining tactics, Ashrock hesitantly purchased the rings from Quark for 199 bars of gold-pressed latinum.
During the exchange, Ashrock was murdered by Fallit Kot, a former business partner of Quark's, who stole both the rings and the latinum. (DS9: "Melora")
