Origin: Vigil the Longest Night
Appearance: The boss is a giant and grotesque abomination, showing female humanoid traits combined with insect morphology. The abdomen especially resembles the one of a giant larva, or of the queen of a hive. Atrophic wings are falling on her back, like vestigial elements clearly unable to lift such a massive figure. The arms are extremely long and dangerous, used as a weapon, especially for the claws at the end. The long neck and the face are the only elements still keeping a sparkle of her female appearance, especially the pale face that resembles a marble mask. However, when her mouth is wide open, the creature shows inevitably her grotesque nature. Her body is curved under extreme sufferance, an amorphous and unfunctional mass acquired through wild experimentations, with scars and stitches covering her body as proof. But the Brood Mother would not be described as a mother without having a progeny, and definitively this is the most grotesque detail about this creature.
Background: The deformed and grotesque creature was not always in this way. The Brood Mother was once just a normal girl, following religious duties, and in love with her boyfriend. Sadly one day, she was betrayed and became the guinea pig of an insane doctor. Her body was subject to twisted experiments, while she slowly lost both her mind and her humanity. Now the pain of those wild experiments is a clear mark on her body, as the twisted path of stitches crossing her body.
The main weapons of the gigantic boss are of course her arms, incredibly long and dangerous, able to easily crush even the most worthy opponent. Her strength is so abnormal and human, that even the ceiling of the cave will collapse under her devastating punches. But as previously specified, the progeny of the Brood Mother is her most dangerous and twisted detail. Small and grotesque infants will be expelled from her body as rounded eggs that, if not promptly destroyed, will hatch in her swarming progeny. The small creatures have deformed bodies fused together like an amorphous mass of sufferance, a sort of sick combination between a fetus and a larva. The void expression on their faces and the infant-like appearance almost create a deep feeling of guilty uneasiness inside the player, who will be forced to slay the apparently harmless creatures. An interesting detail is that, even after slaying the boss, her infants will continue to grow and evolve, from larvae to fly-like monstrosities.
By coming back to the cave later in the cave, the main character will face these new and disturbing abominations, able to spit poison and to self destroy after charging the player. Definitively this time the sense of guilty will disappear. One terrible and macabre detail hinted behind the tragic story of the Brood Mother, especially since the poor woman was in love and having a boyfriend, and the mutated Brood Mother is constantly giving birth, is that probably the woman was pregnant when the experiments started.
