With a glance, you measure the weight of law, chaos, good, and evil in a being or object and learn about its origins and alignment. If you target a creature, you learn the type of that target creature within range. If the creature is celestial, elemental, fey, fiend, monstrosity, or undead you also learn its home plane (if any) and alignment (if any).   Instead of a creature, you can target an object. If you target an object, you can determine what type of creature made it and if it has any alignment of its own.
