Lugh receives a request for assassination. He takes Talt with him and goes to a commercial city, Pisaal. He decides to gather information beforehand to justify whether the target needs to be assassinated. Once there, Lugh saw the suffering of the people that was caused by his target. It's a tragic sight as a young child is forced to sell drugs while her mother was emaciated and was also addicted to it. Thus, Lugh formulates an assassination plan based on the information that Maha had collected. He was successful in killing for the first time in this life, though he soon felt the weight of his action and became emotional after witnessing the wife of the target grieving.
