Symbology of Flesh Kernel

The webcomic Flesh Kernel frequently employs a certain array of "symbols" that have generally some connection to traditional esoteric imagery but have usually an original meaning within the context of the comic.

Leviathan Cross
The Leviathan Cross is a symbol that appears several times in Flesh Kernel, often associated with Wilt. It's composed of an 8-loop (infinity symbol) surmounted by a double cross. It occurs first on "Billy"'s shirt in Fresh Corn, as part of Wilt's link to the Dark Ocean in Xladislax's explanation of its working, and finally on the forehead of Goat Wilt.

Traditionally, it's been associated to Satan in LaVeyan Satanism and has been established as a modern alchemical symbol for Sulphur. Its meaning within the context of Flesh Kernel is presently unknown.

Third Eye
The location of the Cranial Gland of Reticulans and their hybrids corresponds to that of the Third Eye, which is a widespread esoteric/mystical symbol for knowledge or awareness beyond ordinary sight. In addition, the denomination of "gland" itself resonates with the esoteric identification of the Third Eye with the pineal gland, whose mystical relevance in turn stems from Descartes' (mistaken) identification of the gland as the sole seat of the "soul", or rather bridge between body and soul. Similarly, the Cranial Gland opens a channel between the conscious and subconscious plane, and enables a mortal mind to witness what is otherwise unaccessible to the senses.

Heptagrams
The Heptagrams or seven-pointed stars, of which there are two possible ones ({7/2} and {7/3}) appear in Fresh Corn as splash images, bracketing the entire dream sequence. In Flesh Kernel they represent the duality of the Subnatural and Physical plane.

The {7/3} heptagram, representing the Dark Ocean, is also the symbol for the whole Terms & Conditions chapter, since the bulk of the plot is indeed happening "below the surface".

Planetary Avatars
Gods are associated each to a celestial body which acts as their "avatar". The celestial object becomes both a "symbol" for the god but it can also more practically act as an "antenna" or "transmission channel" if the god is dead and thus confined to the Dark Ocean. The avatar acts as a sort of weak temporary physical body with a tenuous connection.

As such, traditional astrological symbols are automatically symbols for the corresponding god, so ☾ is Gnrth, ♂ is Laikalakalaikalakala, and ♀ is Neil.

Exotic Bubbles
Consistent anomalies in speech bubbles mark some profound cosmic particularity about the character. So far, the only exotic bubbles are Mystery Girl's, which are black with white text, and Goat Wilt's, which are double-tailed.

(Other "funny business" can happen with speech bubbles and tails, but it's not meaningful unless it's consistently associated with a character.)

24
24 is the most sacred number of Flesh Kernel. It appears over and over. Kind of an easter egg.
