[Eley gives a nod.] I visit them fairly regularly. It is peaceful up there.

As for your wall... I am not sure if I understand exactly what you are looking for. Since you sound like a newcomer, I can only assume that it is something found in your own world.

[Eley has to wonder just what the importance of this big wall was to him. Obviously it held a great deal of significance or he wouldn't be so adamant about finding it. Somewhere to live? Or work? Or was it for protection from something?]

There is the barrier, though I am not sure if it is really a 'wall' as you describe. We are trapped in an enclosure here.
