Lucin was born a scion of House Wintrish, the result of the illicit relationship between a foreign diplomat and a young noblewoman. Throughout his childhood Lucin was portrayed as the son of one of the recently deceased servants of his mothers house, although his true mother still acknowledged him in private. After his true identity was almost discovered around his 10th birthday, Lucin was thrown out of the house and was forced to survive on the streets afterwards.
At the age of 14 the spymaster of House Wintrish, Adorian Wintrish, discovered Lucin's existence and had him observed, intending to have him eliminated to keep his existence from causing an social scandal for the house. He was impressed by Lucin's potential though, noting that he was a survivor who had a fast tongue and a gift for reading others motives. Instead of having Lucin killed, Adorian took the young man on as his apprentice. Adorian quickly decided that Lucin needed a legitimate background as a cover among the higher society of Korvosa, and therefore he paid to have Lucin educated at a local university.
At the university Lucin excelled in the alchemy and medical sciences, although, unknown to the faculty, his education was being augmented in more illicit arts by Adorian. It was during this relatively peaceful time that Lucin had time to contemplate the forces that surrounded him and had shaped him. His time on the streets combined with Adorian's training about the noble houses of Korvosa had made him aware of strange and more than coincidental connections between the two worlds. There seemed to be a larger purpose to the random happenings in both the streets and the mansions of Korvosa.
Lucin graduated from the university and was named physician to House Wintrish, a position which often gives him reasons to attend various social and diplomatic functions. Lucin is conflicted about his feelings concerning House Wintrish and the greater social structure of Korvosa. He feels a degree personal debt to Wintrish and to Adorian in particular, which Adorian has encouraged and exploited repeatedly. On the other hand he also knows that most members of the house would have had him killed as a child and are unaware of his true identity even now, and he wishes to stop being manipulated by Adorian. Personal experiences have exposed him to the of the oppression of the common man, and of the shadowy cabals that have too much influence in Korvosa.
Lucin is an fastidiously neat young man with longish brown hair and sparkling green eyes. He often wears eyeglasses to increase his scholarly air, although his eyesight is perfect. He also wears somewhat loose brocaded clothing to hide his athletic build.
