Drakmar
From Tatters of the King

Drakmar is a location in the Himalayan kingdom of Mustang that the artist Thomas Villiers intended to include in his tryptich of the Trinity of Hastur. It was the final destination of Quarrie's pilgrimage, but its exact nature was unknown when the investigators left England.
The only mention of Drakmar found in any books about the area so far read by the investigators refers to it as a place from which some emissaries came to the king's court in the 18th century. Once inMustang it is discovered that an alternate spelling of Drakmar is Tramar, but by then it is too late to do any research under that name.
After confirmation from people met along the route that Quarrie was indeed heading for Drakmar, the place was located near to the Nepalese village of Kag, just beyond the Monastery at Te. According to local legend, Drakmar was the place where the Guru Rimpoche slew the ogress Balmo and placed great chortens on her organs to prevent her from coming back to life. The red cliffs of Drakmar are said to be stained with Balmo's blood.
The locals say that the chortens have fallen and Balmo is alive again, and that the ghosts that serve her have been taking people who venture too close.
At Drakmar are found dramatically coloured cliffs riddled with dozens of apparently man-made caves. Nobody seems to know who built these.
