Moon Knight Jones:
What did Neti tell you? Trader Rolento? It is the Dwarf running the store in the Southern Entrance to the Wasteland. So he is the one who signed this Armor Trade Contract?
I always thought him a suspicious man. I mean, such a weird place for the store... So he did that on purpose: to get rid of the guards and sign a contract with our enemy.
Find Rolento, show him the contract and question him. When he admits to signing the contract with Turek Orcs I will send my soldiers to arrest him!
