Lady Merria is a Guild magician who was appointed as Lord Dannyl's second assistant. Merria is a healer and impresses Sonea with the authority she exudes and her ambitions of opening her own hospices, similar to those that Sonea opened in Imardin after the Ichani Invasion. It is alluded to that Merria may have opened these hospices in Sachaka post The Traitor Queen.
|Spoilers from "The Rogue"|
Lady Merria arrives to take the place of Lorkin after he decides to stay with the Traitors. She becomes friendly with a group of old women who have links with the Traitors. Through these links she is able to gain information on Lorkin's welfare during his time with the Traitors.
When Dannyl and Achati organise their trip to Duna, Dannyl asks her to stay at the Guild House in case anything important happened that might need to be solved by a Guild magician. Merria disagreed with his decision, but Dannyl refuses to take her along. Dannyl gives her Sonea's blood ring so that she could communicate with the Guild, and Dannyl took Osen's.|}
