I've got a spell for you......
{Thalassa watched scenes from around the island as she shook a bag of squid bones.
That World Eater and the Vongola made her sick, as sick as his flailing descendant and his lovers made her....but she would change all of this.
She looked inside the bag of the bones and tossed in the appropriate sea plants for amnesia and an aphrodisiac or two. She continued mixing and watching. When she dumped this into the sea it would permeate the entire water supply on the island.
Everyone would forget their lovers and fall for whomever they saw first. It was the perfect way to destroy those that disgusted her....that Family.
She laughed maliciously as she spilled the contents across her mirror and watched it sink across the island. If by chance her spell failed or was weakened by their own abilities she had something even nastier hidden in her scales.......
She cackled and called a storm across the island.}
