Goidemar was the sixth king of Temeria and husband of Riannon. Three years after their wedding, the famous Falka rebellion began, during which the pregnant Riannon was accidentally captured. In prison, she gave birth to twins, Fiona and Amavet, and subsequently descended into madness. At the same time the fierce Falka gave birth to a daughter, Adela, whom she abandoned to wage war, leaving the child for the mad prisoner to nurse. Soon thereafter the rebellion was suppressed, Falka was captured and burned at the stake and King Goidemar regained his wife - with three children.
Goidemar hired several mages to try to determine which child was not his, and they did succeed, but did not tell the king as that would have resulted in the execution of a two year old child.
After Riannon's death, Goidemar lost all hope that Avamet would become heir. He married Adda of Cidaris, with whom he a second son, Cedric who continued the line of Temerian kings which remained uninterrupted until Foltest.
- New Temerian coat of arms had been adopted during his reign: three silver fleurs de lys on black shield.
