Duvianus Platorius is an Imperial who resides in St. Olms Waistworks in Vivec City.

He can ask the Nerevarine if they know where to find Addhiranirr. If Addhiranirr has already been spoken to then the options will be to tell him where she is, say that they don't know, or lie to him. If Addhiranirr has not yet been spoken to then the Nerevarine's choices are either to say no, or tell him they are busy.
