 At the lake Tarn Wadling, Gawain and Guinevere ("Gaynour") encounter a hideous and vividly-described ghost, who reveals that she is Guinevere's mother, condemned to suffer for the sins of adultery and pride that she committed while alive.In response to Gawain and Guinevere's questions, she advises them to live morally and to "have pité on the poer [...] Sithen charité is chef" ("have pity on the poor [...] Because charity is paramount"), and prophesizes that the Round Table will ultimately be destroyed by Mordred.She ends by requesting that masses are said for her soul.
