Devastating assault

Several days later, a shadow suddenly flew over the dark castle of the demon king, Sarganos.

The demons on guard began looking at the sky for enemies, when suddenly the crimson barrier protecting the castle shattered and a gigantic creature crashed onto its rooftop, sending shockwaves through the demon stronghold.

"Sarganos! How dare you mess with my underlings!"

A deafening roar echoed through the castle, terrifying the demons inside. The pressure emanating from the black-scaled monstrosity on their rooftop was like a living embodiment of their deepest nightmares.

"Today, I will make you pay for your sins... Dratharox, come forth!" the figure atop the dragon proclaimed. Suddenly, a wine-like, fleshy substance began to materialize around the castle, engulfing its walls and hundreds of black demons began to appear within the castle.
