Lunar Vigilance

Thanks to hard training, unfortunate health conditions or habits, eldritch or divine gifts, or another reasoning, you no longer have the natural need of sleep.  You are also now immune to sleep-inducing magic.  Your Long Rests now consist of light activity instead of sleep.  Such activity can include keeping watch, reading, talking with another, eating or drinking, and minor effects through cantrips (such as Gust, Presidigitation, Thaumaturgy, or Druidcraft) so long as you know such cantrips.
