A character has a light source on himself, in an otherwise dark area. She ventures in an enemy-ridden area, revealing the position and nature of some enemies as she moves.
How is this ruled?
Should she move square by square, telling at each square the direction she wants, until she wants to stop or she ends her movement?
Should she go on the path she traced before seeing the enemies, at least up to where she could see at the beginning of the round? What happens when she reaches that spot?
