Lutiel didn't make a good impression on Tanas, it was too obvious that he was hiding from someone. And his name was almost certainly not his real one. Despite this, Tanas signed the contract, as the desire for profit was too strong. Besides, he didn't want to make a new enemy, especially if that enemy was one of the dark elves.
After successfully signing the contract, Tanas decided to head to the city's blacksmith. If the task was indeed dangerous, then he needed to prepare accordingly.
