Argonian alchemists of the Black Marsh have long held that the phases of the moon dictate the precise positioning of the Calcinator. During the full moon, the Calcinator should face due South, aligned with the Southron pole star. It is well known that the Southron pole star is slightly offset from true south. The diligent Alchemist will refer to star charts for the specific day and time to more precisely align the Calcinator.
For each night of the phases of the moon after full, the Calcinator should be rotated clockwise one twenty-eighth of a circle. If the Alchemist is closer to the Southron pole star than the Northern Sisters, he should rotate it counter-clockwise instead. Set the device where the moonlight is shining on half of it. Of course, if it is a new moon, the Calcinator should be fully exposed instead.
Proper alignment of the Calcinator will create one part in forty-seven more purity of the distillate. Obviously this is a highly desired attribute, even though the effect may not be that noticable.
