Rusk together with Fist Aguta is standing watch inside the Elfsong Tavern, in its northwest corner. They guard the stairs leading to Belynne Stelmane's private room, blocking access to the scene of the Duke’s murder until Constable Gauntlet Devella Fountainhead finishes investigating it.
When approached by the player character, Rusk tries to be strict and dismissive while turning them away, but Aguta reasons with him, allowing the party to proceed upstairs. This dialogue is enacted every time the couple of guards remain at the tavern, unless Aguta is defeated. In the latter case, Rusk also lets the player character go, telling them that the Fists have their share of problems already.
Rusk (again along with Aguta and under command of Gauntlet Devella, if they are alive) can also be encountered at the entrance to Highberry's Home, in case the player character allowed the serial killer to murder Cora Highberry at the Wine Festival. He is then found yelling warnings to the bypassers, so that they pass the place until the Constable is working on the crime.
