Leodon, from Ultima VI
The Avatar met Leodon drydocked in Buccaneer's Den. Her ship, The Golden Hinde, was under repairs and she was unable to sail at that time, so she was spending most of her time at The Fallen Virgin, although, she admitted to enjoying being at sea much more. Leodon spoke very highly of her first mate Leonna, and the two of them had been acquainted for quite some time.
Leodon was also familiar with Captain Johne, although she believed he had turned traitor and gone to help the gargoyles. Leodon disliked the gargoyles and complained one once stole food right off the deck of her boat while at sea. She offered to join the Avatar's quest to help relieve her boredom.
Runes of Virtue
In Runes of Virtue II, Leodon could still be found at the bar in Buccaneer's Den. She offered to sell the hero important information for 4 gp, and if the hero paid she mentioned how Ybarra had once sailed through a whirlpool and ended up in Lock Lake near Cove.
The Ultima 6 Project
In The Ultima 6 Project, Leodon further explained that when the Gargoyle landed on her ship, she and her first mate Leonna had attacked. All they succeeded in doing was driving the creature into the rigging, which was also destroyed before the creature flew away. Upon offering to join the party, Shamino recommended against joining with the pirate, saying she couldn't be trusted, and that she had left Skara Brae many years ago and forsaken the virtue of Spirituality.
