Azure

Azure is a tinker who, during the time of Ultima IV, resides in Minoc.

He is a carver of runes. Gimble tells the Stranger to ask him of the runes and, upon finding him in Wayfarer's Inn and doing so, Azure will tell the Stranger to ask his sister Mischief.

Ultima V: Lazarus
In Ultima V: Lazarus, even though Azure does not appear, Sir Arbuthnot mentions Azure is his grandfather, and that he got the skills needed to create the Codex Coin from Azure's talent with rune carving.
