Magic:Galdhud
From Zyrkthraan Chronicles Wiki
Galdhud
Galdhud, also known as Old Magic, was brought over by the Fjallmenn when they immigrated from Sheydal. While it is the magic that allows them to shapeshift, it is also considered incredibly volatile, leading to it becoming banned by the Aurilore. The disagreement regarding the use of Galdhud resulted in Fjallmenn society becoming fractured into subcultures that are now antagonistic toward one another.
