Mother

"'Mother is our link between Him and ourselves. We pray to her and she in turn prays to His ear, from her prayer chamber in City One. Mother is gifted the power to control the shape of our world, just like the rest of her lineage. Their blood is that of the angels!' - Yon" "'I am the Mother of the earth. You have challenged the very ground you walk on.' - Mother"

Mother is the currently ruling Medium of the One Concern and one of the three central deities of Tri worship. She is also a boss encountered in City One. She seems to be one of the few characters in the game with full knowledge of Him and his relationship to the Concern and the Planet, but she never divulges this information. She is accompanied by Mother's Corners whenever she appears in public. She seems to have a fascination with cats, and owns a pet named Oedipuss who lives in the Bastion.

=Abilities= As with all Transcendents, Mother has unnatural longevity and the ability to heal rapidly by absorbing Ivory from anything, including the ground. As a Medium, Mother's body was fully fused with Ivory during his Transcendence. This grants her the ability to manipulate Ivory. Unlike Agents, she does not have any prosthesis augmenting her body.

Mother is an older, matured Medium, and her powers likely fully developed, unlike Royal whose abilities are weaker and still developing. Mother's exact abilities are not documented. No Medium is fully able to manipulate Ivory to the extent that Eyes or other components of the Planet can, but Mother demonstrates significant ability to manipulate the world around her. Mother is rarely observed, but she demonstrates her immense power for her, in which she destroys her entire parade float, reassembles the broken pieces into a cat-shaped gargantuan, and not only holds it together but controls the monster she has created telepathically while riding it.

=Story=

Pre-Game
Mother began ruling long ago after Father, likely before most contemporary humans were born as she has the unnaturally long life of a Medium. Her exact age is never revealed, and few specifics are known about Mother's time as ruler before the events of the game. Some rumors can be heard from characters throughout. She rules along with the Bastion Suits, so it is difficult to tell if the actions of the One Concern leading up to the story can be attributed to Mother, the Suits, or both. We do know that both Mother and the Suits have been in league to execute the Escape Plot.

During Game
Mother is mostly an enigma still throughout most of the game. She is referred to, both by true believers and skeptics alike, each giving their own counts of her. She is not met until Robin arrives in City One along with Elro, Mina, and Mother's "son" by right of Transcendence, Royal. At this point, Royal has already destroyed the Omega Controller and accidentally summoned Him to the Planet earlier than Mother and the Bastion Suits could finish their escape plan, so Mother is angry with him. They meet in public, so Mother tries to calm Royal down rather than show her anger in order to prevent causing a scene in front of all the bystanders. Royal and Mina insist on discussing their quest immediately, and they shout things that she intended for the public not to hear. After having no success in silencing Royal and Mina, even while promising to meet in private shortly, she eventually loses her patience and attacks. (See: )

Using her Medium power over Ivory, she turns her float into a cat-shaped monster. Robin and Mina fight her, with Robin damaging the cat-monster and Mina hitting Mother with her Seeds when she is knocked off. Eventually the seeds start to react to the Ivory in Mother's body, preventing her from healing.

Just as she is too weak to continue fighting, General Chrome and the One Concern Army walk into the scene. Chrome believes her defeat to be His will due to her deception in the Escape Plot. He then proclaims his intention to lead the One Concern into a new era free of such corruption. Just as he is explaining how this is His will and that mother's death is because of her sin, the seeds inside her explode into a tree, killing her. Chrome mistakes this as a divine sign of His will and providence for his path.

=Trivia=
 * Mother's soundtrack's title implies that both her pet cat and her cat-shaped weapon are named "Oedipuss".
