Iokaste was once briefly smitten with a gentleman named Gannis Frostmantle who visited Waterdeep and claimed to be an emissary of the Tuigan horde from the distant lands of the Endless Waste. Gannis courted the widow and asked her help in finding people to fund his campaign against demonic intruders. He insisted he did not need her money, of course, but she would not hear of his refusal. A well-traveled woman, Iokaste added a drink to the menu of the Flumph that would remind Gannis of home: a salted yogurt-based drink that was popular among the horse riders of the Hordelands. Gannis tried the drink and spat it out, and that was when Iokaste realized he was a fraud.
In a rare instance of solidarity between Iokaste and Wishes, they arranged a visit for Gannis with the wrathful gods of the Hordelands—or at least an illusory approximation. Gannis was last seen heading for Luskan. The Hordelander cocktail remained on the menu as Iokaste had developed a taste for saltiness.
