The Abyss Empire was facing a greater crisis than they initially anticipated.
A simple border skirmish turned into a border war. It was still bearable. Abyssals had fought too many wars with the Fairies in recent years.
But things took a drastic turn when strands of death energy started to pop up in the Fairy Army.
The dead members from both sides became the Undead and were used as the vanguard against the Abyssals' Blood Province.
Blood Province was fortified enough that if 100,000 Abyssals defended it, the enemy needed to bring in at least 200,000 attackers.
Even with the addition of Undead, Fairies didn't have that number.
So, the Abyssals thought they were safe. But reality slapped them in the face when one of the Fairy Sovereigns used a concentrated strand of death energy on the defense.
