Captain Saltay is a high-ranking member of the Sharn Watch, as well as the direct superior of Monster Squad. As his rank implies, he is one of the most powerful figures in the Sharn Watch, and reports to the Council directly. His duties seem to include reviewing reports, managing Monster Squad’s funding, and dealing with PR problems that the Squad faces.
In the campaign, he’s the one who assigns cases to Monster Squad. He provides the initial information that the Squad needs to investigate the situation. His interactions with the Squad always occur in his office.
He has a somewhat strained relationship with Zixzax, since he keeps asking for expensive equipment that Saltay insists the Watch can’t afford. It’s heavily implied that Saltay is a corrupt cop, considering how lenient he is with Monster Squad doing illegal things (like selling their official tabards to shady people) to get funding for more equipment.
