Og's Spine

The greatest mountain range in all of the Realms, Og's Spine spans from the Celestial Seas in the north of Ognaris, to a point near the south-eastern coast.
It is believed by many of the tribes in Ognaris, as well as the people of the Mountain Holds scattered along Og's Spine, that the mountain range is all that remains of a primordial giant named Og, who fights off the earliest Divines to attack Iona in many local legends.
