Aldo and Hector - NWN Side Quest (Chapter 1)
Aldo and Hector is a quest that takes place in the Beggar's Nest map of Chapter 1. You'll find Aldo and Mattily guarding their defunct wagon in the middle of the map; to begin this quest approach Aldo and talk to him. This quest is one of the easier ones to complete on this map, all you have to do for it is visit Thomas Wheelwright's Wagon Repair shop in the southeastern portion of the map.
Inside the Wagon Repair shop you'll find Hector whom was unable to find anything to repair the wagon. Speak with Hector and he will ask you to escort him back to Aldo which should be easy enough considering you probably killed most of the Zombies in the area.
Note: Search the containers inside of this building for an Official Document item. This item is involved in Tomi's Tale which is his Henchman quest.
Once you lead Hector back to Aldo all that you have left is to speak with Hector to complete the quest. You'll be rewarded a small amount of EXP which varies depending on your level and that's it.
