Well, it's called "Kala"... so I can only imagine it is an as-yet-unseen place, and (yes) probably in Arana given that area is a mountainy sort of area.
There's a Kala Close in Jethimadh, but it's nothing like that.
I live in Aranna. I was the first on my street to move in there. Maybe even the first in Arrana. And it is beautiful. I just wish there were bigger houses available up here.
