The Wormgod         

Day 4 dawned in the virtual realm, and the Castle of Doom loomed ominously on the horizon. 

The guild members, fueled by Ragnarok Reaper's rallying words the night before, gathered once more in their designated formations. 

The tension from the previous days persisted, but a renewed determination sparked in their eyes.

As the clock struck zero, signaling the commencement of the fourth day's battle, the guild leaders swiftly implemented the strategy and formation.

The players anticipated the arrival of the enemy, their attention undivided. Suddenly, the horizon darkened, and an ominous stillness settled over the air, carrying with it a putrid scent of decay.

Every breath was held as, in the far reaches of the virtual landscape, an entity materialized. 

As it drew closer, collective gasps echoed through the assembled players, taken aback by its gigantic size and repulsive appearance.
