Taliesin

Taliesin is a bard from Mondstadt in Genshin Impact who joins the Chasm Exploration Team, seeking to record new adventure stories. He can be found in the Underground Mines of The Chasm. He is also a key figure in the hidden achievement "The Tome of Taliesin," which requires players to complete a series of quests and then speak with him, sharing their adventures in the Chasm, in order to obtain the achievement. The character design of Taliesin is likely inspired by the medieval Welsh bard of the same name.
