Forum:I have many questions that id like to ask?

One: Id like a list of all the different races/tribes of middle earth.

Two: Is there a map that actually shows all of middle earth and the other islands where the elves came from etc?

Three: How come on this wikia there isn't a tab at the top explaining locations and races?

Four: What happened to the Nazgul after the destruction of the ring?

Five: Why did all the orcs die after the destruction of the ring?

Six: Who inhabited the far northern area above the mountains where the dwarves came from?

Seven: Who inhabited the east of "Rhun" and "Mordor"?

Eight: Who inhabited the Far South below "Mordor"?

Sorry if i have posted this in the wrong section or if any of there answers are on here, im new to forums and wikia so dont know how to find out the things im looking for.
