Mathias is an old man and wizard that sets Nasir out on the mission of cleaning the water in Lakeland. He drops in randomly to set you on another mission or to give you hints. Mathias is also seen in the game opening.

A blue dressed old fat man with moustache in Atland whose name is not told says this when you speak to him:

Hey, NASIR! Long time no see. How’s MATHIAS? MATHIAS is a great wizard. You must use magic as well as MATHIAS or you’ll never be a great hero.
