When the Mane Six receives a desperate plea from the coastal village of Seafall, they uncover a mysterious and horrifying plague tied to an ancient, enchanted well. The infection begins subtly-a thirst that cannot be quenched, tears that shimmer like liquid crystal, and hair that flows unnaturally like water. As the plague spread, the Mane Six succumbed one by one. Pinkie Pie's once-bouncing mane drips endlessly, Rarity's cutie mark shifts to haunting pearls that call her to the ocean's depths, and Twilight Sparkle's logical mind begins to ripple with unsettling whispers. Their transformations turn them into eerie, water-like versions of themselves, their glowing blue eyes reflecting an unnatural call to the sea. With no cure in sight and the infection spreading faster than they can contain it, Rainbow Dash and Applejack must race against time to save their friends before they too are lost to the tide. But as the Weeping Well overflows, a chilling truth begins to surface-this plague may have origins as ancient as the two sisters themselves. In the foggy streets of Seafall, nothing is as it seems. Can friendship prevail when the very essence of who you are starts to melt away?

[I clarify: like all my stories and the one about ''Big city infection AU'' I wanted to grab another animated series by making an AU of infection, I have nothing against the series but it is too childish for me so I have come with this original Au] [The cover is made by me]
