Their story is actually really great: She (Ronnie) and his love, Sir Noster were both knights of the Phoenix house. Ronnie was chosen to become a Protector (there are always 4 of them, the best knights who become the king's guards). However, in that time we had an evil mage king, and she was severly wounded in one of the raids. The king turned her into a lich, and closed her soul into a medallion. Sir Noster could not believe what his wife turned into: she drank the blood of innocents. So he went on a great journey to find a cure, and learned that if he kills the mage king, and breaks the medallion, she will come back to life - but on the price of his own life. He sacrifized himself, and she lived.
But their torment was far from over: the servants of the mage king reanimated his body to torment her, he came back as a deathknight. She did everything she could: even went down to the Abyss to find her lover's soul, but finally they had to kill the remains of her husband. Now she was completely alone, again. But she remained strong, and worked hard to save the kingdom. She was the first one in a long time who did not inherit the throne or killed the previous king to become one: she was chosen by her people.
