I did. Anyway, here is what you could know about the Overworld based on what Laakmub can tell you.

The exact nature of the dimension, and how it operates

The extent of the Orcish civilization

The existence of the Nether and Him (though they call Him the One with White Eyes)

The appearance and behaviour of the Endermen (though you believe them to be called the Shadow Wardens.) You have enough info to know that Eureka is one.
