An interstitial eclipse is the interposition of any number of planetary bodies between a planet and a star. In the case of Premthoth, this eclipse is visible at night because the eclipse occurs when seven of the planets (Enochii and the six inner planets of the Tefireth system) are in the Kesermost decant of their orbits around Tefireth. The eclipse appears as a six-pointed star or hexagon on the brown-red background of the infrared dwarf star. Other instances appear as irregular polygons, triangles, squares and pentagons.
