Helie
Elene, Elias, Elie, Heliae, Helie, Helies, Helyes
The lady-in-waiting for Queen Esmeree the Blonde of Snowdon.
When Esmeree’s city was cursed by two sorcerers, Helie traveled to Arthur’s court to find a knight to save her lady. She was infuriated when Arthur gave her the young, inexperienced Guinglain, who at that time was called simply Fair Unknown.
Helie and her dwarf, Tidogolains, rode off in a huff, but Guinglain pursued them and convinced them to let him try the adventure. Helie realized she had been mistaken about Guinglain when Guinglain proved himself worthy in a number of combats, and when he eventually completed the adventure and freed Esmeree.
