Ring of Blue Fire

The Ring of Blue Fire, previously known as the Ring of Gray Flames, was a series of ruined towers found in Rashemen, that dated back to the ancient empire of Raumathar.

Description
The five towers of the ring were set in a circular arrangement each of which was topped with corona of gray flame. Each of the remaining towers emitted strange mechanical sounds and radiated strong magical auras that disrupted the casting of any form of divine magic within a radius. Additionally, the towers' flames lashed out at anyone that attempted to conjure any extra-planar beings from beyond the borders of Toril.

As of the late 15 century DR, the continual gray flames were transformed into jets of blue fire that erupted sporadically, accompanied by a bright light that shone from within the towers.

Geography
The towers were located on the edge of the Endless Wastes, about three day's of travel by horseback east of Mulptan.

History
By the, only two of the five towers remained whole and standing.

During the Spellplague, in the, the flames erupting from the towers became more intense and changed from their gray color to that of the blue fire associated with the cataclysmic event. They took on the same transformative properties as the blue fir, causing nearby creatures to develop spellscars or even transform into plaguechanged horrors.

Rumors & Legends
Many people believed that the towers were a source of ancient Raumathari battle magic.

Inhabitants
The lands surrounding the towers were inhabited by roaming spells that seemed to have a mind and will of their own.
