He spent the first day just getting the layout and what patrols there were, if any, the second day actually making a decent map of the city while confirming the patrols, and then on the third day he start picking spots to place the smoke charges will confirming again what patrols went where. He also noted when most of the drow seemed to be resting, so he could start the attack then.<br/><br/>On the forth day, he would head into the city, acting like one of the lesser creatures in the city, though he would avoid confrontations at almost all costs, though he didn't want to spread alarms. If all went well, he would have all the smoke charges placed throughout the city, as well as severing some of the light orbs, when he was ready to hit the city on the tenth day.
