Magic Dead Areas
From AmtWiki
A Terrain Type as described in the Tales from the Vardo
These areas, through accident or design, are permanently under the influence of an Anti-Magic spell. No magical effects may be initiated or allowed to pass through these areas: spells fizzle, enchantments vanish and relics cease to function. Enchantments reappear intact once the bearer leaves the Magic Dead Zone. Non-magical Class and Monster abilities function without penalty.
