Virilus  

I believe you're thinking of Anilius. Virilus spawns with Favonius Facilis in the main room. He has a few Malevolent Disciples. He's harder if you're prepared because the disciples are harder than the wraiths. If you don't prepare, Anilius is harder because you'll find out the hard way that there's a nuker called Insideous Whisper that regens around a corner right before Anilius and needs to be pulled and killed before Anilius. All conned yellow to a lvl 15 cabbie, and killed both without much problem although it took a little strategy due to their little friends.
