In a dark alley at night, you are attacked by thugs. Before they can take anything, they turn white with terror and run away. You discover that you have a guardian ghost, a wise, benign spirit who accompanies you (work with your DM to determine details)
You spend time with a spell-caster who teaches you a minor cantrip as a parting gift, learn one cantrip from a spell-casters spell list (DM's Discretion)
