The NΓH U is a location seen on a sign in King's Quest V (NES).
Background
It is not entirely clear what the meaning of the sign is. But it could be something along the lines of a university.
The first three letters appears to have Greek letters, thus it could be Nu Gamma Eta University.
If a university this maybe the Serenia university to which the Desert Bandits once attended.
Behind the scenes
Alternatively based on its its similarity to the North Inn sign's graphics, it could be reused assets and could be a smooshed version of "North"
