Over the years, Envis had observed the Ribina species flourish, but his hostility toward them had grown steadily. As October arrived once more, he resolved to take action. Years of honing his powers had revealed that his abilities were most potent during the full moon. As another such celestial event graced the current month, Envis began preparations for his nefarious scheme. Crafting spells, curses, and intricate plans would consume his time, for he knew that orchestrating this intricate plot would require careful consideration and meticulous planning. 

As the days passed and the full moon's date drew nearer, Envis delved deeper into his preparations. He secluded himself in his dimly lit chamber, surrounded by ancient tomes and arcane artifacts. The flickering candlelight cast eerie shadows across the room as he pored over his grimoires, searching for the most potent incantations and curses.

His hatred for the Ribinas had grown into an obsession, and he relished the thought of wielding his powers to bring them to their knees. He contemplated the nature of his revenge – should it be a malevolent spell to cripple their existence, a dark curse to haunt their every step, or something more sinister?

Envis meticulously mapped out the phases of the moon, aligning his dark intentions with its waxing power. He knew that timing was crucial, and he intended to strike precisely when the moon was at its zenith, granting him unparalleled magical prowess.

Each night, he practiced his spells and refined his plan, ensuring that every detail was perfect. He created an intricate web of illusions, traps, and barriers to shield himself from any potential threats during his ritual.
