Dandelion (Polish: Jaskier, supposed real name: Julian Alfred Pankratz viscount de Lettenhove, although the title might be false) — a poet, minstrel, bard and the closest friend of witcher Geralt of Rivia.
Remember the scene in the books where Geralt tells his companions the mile-long name he would have picked? He says Vesemir told him that was ridiculous and that now he agrees. And Dandelion? Dandelion smirks at Regis, who feels offended, and Cahir, who is also miffed.
I choked with laughter when Dandelion was addressed with his real name later. Literally.
