By the Light of the Moon (TCG)

 By the Light of the Moon  was an air invocation which allowed the shugenja to briefly change the quality of light in the area to that of a moonlit night, granting illumination of the affected area for those inside and unweaving the shadows to lay bare the things they concealed. Hidden objects glow faintly with silver light, while mystical illusions were revealed as translucent, gossamer forms.
