City of the Bone Mountains
A far eastern city guarding a pass through the Bones.
The fuller tale
This far eastern city guarding its pass through the Bone Mountains sits so remote from Westeros that the Dance of the Dragons would need to travel further than almost any war in the storyÔÇÖs geography to reach it at all ÔÇö which is to say, it never really does.
The fallen of this place ÔÇö if any, they are named here. Spoilers.
No death the chronicle records has come to this ground ÔÇö or none the maesters have set down.
