Marqiroth Dracona

The most Northwesternly point of The Enclave of the North is Marqiroth Dracona.
Marqiroth Dracona is dominated by incredibly vast mountain ranges, thick forests and deep caverns. The mountains range from rocky mountainous forests to windy, towering cliff sides to gargantuan icy massifs. The region is populated by metallic dragons who (it is widely believed) were in hibernation for almost all of the First Age.
Unlike Ancient Dragons, Metallic Dragons are sociable and generally good entities, choosing to worship Bahamut and condemning the chaotic violence of Tiamat.
The largely Dragonborn population of Sol Dracona are the sworn protectors of the region and vow to represent the Dragon's interests in the Enclave of the North.
The dragons of Mariqroth Dracona are fearful of and disgusted by the Tiamat Sanctuary and seeks to protect not just themselves but the entire Enclave of the North from those in the Scaled Islands.
