In his position as a priest of the Dark Religion, Mardrash possessed a rod and amulet of power, both bearing the sign of the Eye. The amulet had to be worn on the forehead while using the rod for it to exhibit any sign of Black Magical power. The rod acted as a spell power enhancer for all Black Magical spells. The use of these artifacts, or, indeed, the use of black magic spells, had a corrupting effect on the user. Any adventurer who retained these items and used them to cast Dark spells found his actions and his attitudes affected, slowly being seduced to the lure of evil. These items had great resale value, though, fet-ching upwards of 1200 gp apiece if the seller patiently searched out an appropriate buyer (a Lord who secretly wanted to skill himself in the Dark arts, for example).
