Nal'shin was the name of a location on Vulcan and situated in the Tat'sahr province.
It was a valley that was the source of many skirmishes during the warring days of the Vulcan race before they embraced the logic of Surak. Nal'shin was present in between three inactive volcanoes and was a fertile region which allowed for the growing of food, gathering of minerals as well as a small amount of water. Thus, it was the prime target amongst fighting groups which was why Fort Aba'kur was established at the entrance of the valley where invaders were repelled from taking over the valley.
