I went all throughout the asylum, talked to Serran? I think his name was, he babbled on about the cure, and taking over the world, but I dont see any way out, If wondered everywhere! help!

Hello Indiglo!

In the room where you encountered Scabban there is a hole in the floor. You will fall into a pool underneath this room. But before you jumo: Pull the lever on the wall close to where Scabban stood when you encountered him. This will remove the bars blocking a further dive into this pool. This dive will lead you into the next area where you can swim to the Tomb of Nivius to receive the Signet of the Mavin.

Hope to have helped.

Greetings,

THE ONE
