among the youngest of her generation Mayall mainly stayed separate from the death of the previous generation, it all told to her second hoofed. Dominated over by her sister Bernice, Mayall would retread into herself, and become an avid-reader of whatever books that the lurkers had recovered, getting lost in simple foal books. things would change when the her mother Andromeda would find and crack a hidden vault, inside was a small library, all preserved by old magic. Practically diving in, Mayall would come to learn high literature, ancient classics, and even the history of their world, all unedited from the time they know as the Grate Pony Death.  
Becoming a romantic, and wanting to share the books with others of her kind, Mayall would start coming out of her shell (Figuratively… Molting dose not count) and though her books had become more eloquent then even her mother, though lacking the same level of confidence. Soon after, Lurkers would start gathering around her, following her lead, and educating themselves as she had, off of which began to threaten Berenice’s own hold of power. Berenices would become even more aggressive towards her sister, treating her more like a possession then as family, and would threading anything Mayall loved if she didn’t stay in her sister shadow.
 
Turning to one of her closes lurker friends, Turnip Soup, he would suggest hiding away the things she loves, so that Berenice could not destroy them, when asked where, Turnip told her of an underwater boat they had found, it only needed to be dug up, and turned on. Mayall would then give Turnip and the rest of her followers the order to do just that.
 
Some time later their nest would be disturbed by ponies, a battle along the topside that would set a tall building on fire, all examples of how dangerous ponies were, and worse, they had found their way into their nest. Worst still, a second part of that group would be lead inside by Turnip. One pony called herself Princess Harp Melody, and had managed to gain their others mercy, even if Berenice protested to it, and tho they were let go, one was made an example of, and Turnip was banished by Berenice’s request.  
Being told she could not see her closet friend again was the last straw for Mayall, and so she would leave her nest in search of Turnip, then they could leave the island in the underwater boat. This would not happen, and Mayall would become part of that pony group, endure hardships, and grow further before finally leaving the islands for good.  
-Her longer fins, and pink glow come form direct contact with a megaspell, mutating her into a somewhat taller sparkle-lurker, also changing her natural perception dampening field, into a electromagnetic disruption field, confusing technology on a low level, but when in contact with the raw magic of Harp Melody, they produce an electromagnetic pulse, that can overpower most tech in a short distance. the effects of her new magical state on normal creatures are unknown, but some of those around her for an extended period of time experience nausea, dizziness and a metallic taste in their mouth, also phonologically to them her glow seems to become brighter, dispirit her not actually becoming brighter, as well as they feeling more compelled to just lessen to her, and irritation when disturbed.
 
After leaving in the submarine, Mayall would use the maps inside the sub to locate safe locations to start new nests along the Equestria’s western coastline, and though each colony is small, they are protected by the mierlurks they brought with them, all from inside the hidden submarine bunkers they now call home. Mayall herself would continue to live in the submarine, protecting her followers, and endlessly surching for her new friend Harp, who had become lost.
