Lucas is a witch working for Thomas. He has a tendency to make fun of people while standing upside down. When Yardley Pack moved to Crescent Lake, Thomas gave his magical energy to Lucas to send a threat to the Ross Pack and poison Elias and Sara with wolfsbane.
Unlike most of the pack, Lucas's hair is blond and pretty much straight, and his eyes are pale blue. His height is difficult to judge, but he appears to be about the same height as Elias. He wears tattered clothing and old boots.
Lucas is a bit of a prankster with a puckish sense of humor that others around him don't find humorous, especially Thomas, his alpha.
Not much is known about Lucas, except that he followed Tom out of Ohio, and he might be dating Ella.
