Ghroth, the Harbinger, is a rat renowned for his singing voice. When the Dunwich Horror was forced into an early retirement Ghroth stepped up, and out of Arkham, to join the team. He is now usually the first person on the field, announced the team's arrival in a beautiful tenor and making sure the team doesn't oversleep. He's also responsible for a number of musicals, all of which tend to star him and tend to drag on for quite a while. Long enough that the audience tends to not care when the people sitting beside them start to disappear.
