The whole setting behind this pic is Nimeral is assassin. Trying to take out a target she's been hunting for awhile only to be going up against counter parts, she finally gets the original target while finding his scroll that allowed him to make body doubles. Meanwhile a guard comes up after hearing some sounds to investigate and find her.
