Role in the series
Quirin is a close friend to Corona's king, Frederic. He also worries for his son, as most of his inventions lead to trouble, sometimes life-threatening, despite well-meaning intentions. As the number of the black rocks continued to grow to the point of destroying his village, he promised the villagers that he would alert the King of the predicament. Varian went with him to Corona and saw his father lying about the state of their village; as he began to believe that Quirin is running away from their problem. Quirin saw this and told Varian to, once again, stay away from the rocks and refrain from interacting with them; in which Varian disobeyed.
When Quirin got sealed in the amber caused by Varian using an alchemical solution on the rocks, along with the letter that he had written to his son, Varian had made it his mission to save him, no matter who or what got in his way.
In "Secret of the Sun Drop", it is revealed in a flashback that on the night of Rapunzel's birth, prior to Frederic's acquisition of the Sun Drop Flower, Quirin had warned the King against removing the flower, would cause unimaginable consequences. In the present, Varian uses Rapunzel's hair as the tip of his drill in his second attempt to free his father, only for it to fail once more. After Varian's defeat, Frederic vowed to find a way to free Quirin and help his son.
