The Invasion of a Powerful Enemy

Large Battle Scenes, Unforgiving Enemies, Bring it On!

The demon leading the invasion is known as Xyrathax the Destroyer, a massive and terrifying entity from the depths of the underworld. Its armies are made up of a wide variety of demons and other dark creatures, including powerful fiends like balors and pit fiends, hordes of lesser demons like dretches and manes, and even corrupted mortals and beasts.

The summoning process of a powerful demon from the underworld can be a complex and dangerous endeavor, requiring rare and exotic materials, forbidden knowledge, and often the sacrifice of innocent lives. As the players investigate the impending invasion, they may come across various clues and hooks.

Xyrathax has several powerful followers, each of whom serves as a leader and general within its armies:
Razeen the Ravager, a balor known for his brutal tactics and love of destruction.
Malgath the Betrayer, a pit fiend who delights in sowing chaos and discord among its enemies.
Zalzax the Corruptor, a succubus who uses her seductive powers to turn mortals against their own kind.
Kethrax the Deceiver, a shadow demon who excels at sabotage and assassination.
Azrax the Bloodthirsty, a glabrezu who revels in slaughter and violence.
