Wall of Erenyn

South of Boreg stands an ancient edifice called the Wall of Erenyn. This curved metal wall is 3 feet (0.9 m) thick, reaches a height of 15 feet (4.6 m), and stretches more than 100 feet (30 m) in length. It shimmers with a cascade of colors and shapes. Occasionally, the wall shows comprehensible imagery, and many believe that it foretells the future, prophesies, or conveys vital secrets to those who need to know. Spending too long in the vicinity of the wall can make people ill, sometimes to the point of death, so visits are usually short.
