Virgil (U4)

Virgil is a mage living in Trinsic during the time of Ultima IV.

Description
The Stranger could find Virgil in the midst of an array of poison fields. Speaking to the magician would reveal that he specialized in creating such magical fields - with poison being his favorite. Following a tip from Arron from Vesper, the Stranger would know to ask Virgil about the location of the elusive reagent nightshade, and the wizard could tell the hero that this rare hallucinogenic fungus could be found only in the darkest of nights, at the coordinates lat-J'F" long-C'O".

Trivia

 * The name Virgil is an anglicised version of Publius Vergilius Maro, the famous Roman author who penned the Aenied. Unlike other characters in Ultima IV named for famous authors, however, Virgil does not appear to quote his namesake at any point in his dialogue.
 * When the Japanese developers ported Ultima IV to the Famicom/NES, Virgil's name was translitterated in a form similar to "Vi-ra-ji-lu" or "Bi-ra-dzi-lu". Later, when the game was localized into English, "Bi-ra-dzi-lu" was rendered as "Brazil" or "Basil", in two different dialogues.
 * In the Nintendo port of Ultima IV, Virgil-Basil was moved to Moonglow. After the hero was prompted by a barkeep, the mage still revealed the location of nightshade fungus (at 149, 46 when both moons are new). His original spot in Trinsic was filled by an unnamed wizard who explained the composition of the virtue of Honor.
 * In the novelization of Ultima IV in Ultima: The Avatar Adventures, the mage lurking behind the group of poison fields is Swindrik (whose name is misspelled as Sendrick), rather than Virgil.
