Lachtopher wanders the northern part of Lumbridge, usually outside the General store. He is the good-for-nothing brother of Victoria who once lived on the east side of the River Lum until goblins invaded his house. It is presumed that his house was closest to the border gate of Al Kharid. The other one was most likely house of Lozar, due to the population of goblins in that house.
Jagex may have included Lachtopher in the game as a way to satirise players that beg, and to show new players that begging is not a good way to make money, as they may face criticism.
He is the first NPC to talk to in the Cryptic Clue Fest of the 2009 Thanksgiving event. You must have 3 ropes, 2 buckets, and 5 bananas to progress in the event.
Lachtopher is Victoria's brother. He used to live on the east side of the River Lum until goblins attacked Lumbridge, forcing him to move to other side of the river. Victoria decided to take Lachtopher into her house for a couple of weeks, as her mother always taught Victoria to be understanding and kind. He has stayed there ever since.
