Sylvian

The Old God of Love and Fertility. She makes no appearance in the game (she is only seen in pictures), but has an important role and influence upon this world.

Lore
The Goddess of fertility, love, lust, and creation. She is one of the old deities worshipped by man, before man decided that they had enough of the old world order and wanted to supplant the Old Gods. Like Gro-Goroth, the god of human sacrifices, she comes from the green hue, the place where the Lady of Moon, possibly the Maneba, possibly the Pocketcat, the Trickster Moon God, and maybe even the God of the Depths come from.

She created men and women at the dawn of time, the creation of the world. Because of this, she could be seen as a Mother Goddess, the one that brought life to everyone in many ways, while Gro-Goroth, her opposite, brought death to everyone in many ways. A beautiful balance and duality one can say from reading about the two.

Sylvian wishes for men and women to make love in her name. But what kind of love she wants, is interpreted differently by everyone. Some take it literally and show love to each other in a form of marriage. But not just any marriage. A beautiful marriage of flesh or for three. A holy bond and 'beautiful unison for two souls' or three souls. Some form sex cults like the Bunnymasks in their hidden courtyard, having an orgy of sex with each other, to honor and to do it in the name of their Old Goddess, Sylvian.

The twisted realities of these different kinds of love is because Sylvian realized that the men and women she created would not be able to return the same amount of affection towards her as she does to them. Her love is a more twisted form... as shown by the example of the Marriage and the Abominable Marriage.

It is unknown when she has left the world, but it is known that she is the first of the Old Gods to have disappeared from the world, most likely followed by Gro-Goroth afterwards.

The Traces of Gro-Goroth reveal, after defeating it in battle, that the Old Gods the humans knew have left the world because of humanity's selfishness and ambition towards usurping their position, and that they understand nothing about the purity of the ideas the Old Gods have. But even if humans did have a glimpse at such an idea, they would not be able to comprehend it, as seen in Ending B...

Her symbol is the shape of an opened eye. In Fear and Hunger: Termina, her symbol has been changed and is now represented as a vertical slit. Could be interpreted as an eye, or a vagina.
