Arnon - The Queen of Decay

This mythical creature goes by several names including Arnon, Queen of Decay, Lady of Rot, Mistress of Mushrooms, and goddess of Fungus. She originates from the Abyss and vows to conquer the surface dwellers, destroying them and engulfing them into her undead army. Complete and utter annihilation of all living creatures and absorbing them as food for her fungal kingdom is her singular focus.
She has several symbols that represent her religious cult, one of which is a crescent moon covered by a beetle made out of skull. Another of her insignias is a skull with a mushroom growing out of the top.
Arnon's number one rival is Lolth - The Queen of Spiders who forced Arnon out of her realm.

ARNON'S LULLABY:

Fear not for your future,
for now you must sleep
In Arnon's Cradle your body shall steep.
Your flesh a fine banquet of delicate food
Your gift to the Lady shall nourish the brood.
What births from your leavings and grows in her nave
Shall feed from your ruins and fat from your grave.
