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"
