Connwaer is a thief of the Twilight, a desolate part of the city of Wellmet, teeming with pickpockets and thugs. On the run from the city’s Underlord, Conn steals a banished wizard’s power stone, his locus magicalicus. Nevery, the gruff wizard, becomes curious when the stone that should have killed Conn, has little effect on him at all. Will Conn find his own locus magicalicus and save Wellmet’s dying magic?
