At the entrance to the mines

[Arwen Imladris]

So they were good friends, I'm not going to tell my best friend the number combination to the security keypad, and I"m sure you ain't either, it's the same thing.

But those were better days, Estelyn Telcontar already proved that. They didn't worry as much.

The Elves of Eregion probebly didn't want to go all the way around the mountain to get to the front door.

Even so if dwarves and elves likked each other, wouldn't the front door of the dwarves castle be in Dwarvish?(what do you call the Dwarf language?)

It wasn't the front door it was the back door, I think.
