Trivia
(NB - there is a spelling difference between in-game Taliesen and the Welsh name Taliesin, probably for the same reason as the common "Sir" in the game is spelled "Ser")
 * Taliesin seems to speak with a Fereldan accent. It is far removed from Zevran's, which suggests he is not native to Antiva.
 * Taliesin is voiced by the same voice actor that voices Fenris in Dragon Age II.
 * Zevran speaks Taliesen's name phonetically, but the Welsh name is actually pronounced "taleeESin".
 * Taliesin is the name of a scientist who was killed by a rogue VI in another of Bioware's games, Mass Effect 2. He appeared in the N7: Abandoned Research Station side mission.
