Leona

In Ultima V, Leona is one of the two sisters who care for the Temple of the Virtues in Cove.

Her sister Ava, if asked about the Shard of Falsehood, directed the Avatar to ask Leona about her "vision". This vision provided directions on how to get to the Shard of Falsehood from the Underworld exit of Dungeon Deceit: first southwest across many tall peaks to a system of caverns, then continuing southwest until turning northwest at "a major intersection", "soon branching northeast". A long journey northward, then the passage turns west. Then rocky hills to the southwest, then to the northwest. Over a lake, past a massive series of falls, to a bigger lake. On the bigger lake is an island where the Shard of Falsehood lies.

Ultima V: Lazarus
In Ultima V: Lazarus, Leona is blessed with the uncanny ability to see the present with clarity, and is highly acclaimed amongst the Mystics of Cove. In her youth, Leona, her younger sister Ava, and an unnamed eldest sister were left at the steps of the Temple of Virtue, and had refused to be removed from its grounds. The girls grew up at the Temple, and Leona helped care for the Temple along with her sisters, keeping the grounds, and seeking donations for the upkeep of the Temple, so that seekers from across Britannia can come to the grounds and meditate upon the Virtues.

Leona was able to describe the present in great deal, speaking highly of Carolyn at The Candlelight Inn, Jessica, and Enlor. She reported having a vision of a shadowy figure with flaming eyes which could not be distinguished when she met Vortigyrn at the Temple, and felt that Ivar was a man who suffered a great pain, but was also filled with deceit.
