Nanda Parbat is a hidden city nestled high in the mountains of Hindu Kush.
As Rama's agent, Boston wanders the Earth performing good deeds in hopes of eventually accessing the afterlife.
A map had been used to reach this place in the story arc The Resurrection of Ra's al Ghul written by Grant Morrison and Paul Dini.
The map is supposedly composed of seven pieces, including a tattoo, a scrap of parchment, a poem and a birthmark.
It is home to O-Sensei, who ran a martial arts dojo, as well as a gate to the god Naga's dimension.
