Marvis is a Lupe that lives in the village of Trestin. When Rohane went off on his adventures, she expressed her feelings that Rohane's father would have been proud.
It's too bad that your father isn't still with us to see you going off to adventure. He would have been so proud of you.
As most of Neoquest II takes place inside a computer simulation, it is unclear if Marvis is a character in the real Neopia.
