Abaddon (Swarm)

"And a king ruled in the darkness; an angel of the bottomless Abyss, His name in the Hebrew tongue is Abaddon."
Revelation 9:11

Once a celestial creature and a powerful force for good in the world, Abaddon the Destroyer now seeks only destruction. After the fall, the angel once known as Abaddon became bent on wrathful vengeance toward the hierarchy of good that he once served. This inclination to wanton violence eventually consumed his mind, driving him into a mindless and destructive rage. The sin of wrath fuels this power. Any time a human strikes out with vengeance toward their neighbor, Abaddon's power grows. This power is a consuming obsession for Abaddon. Although the magic of sin has granted him powers that surpass those of Lilith herself, his consciousness and even physical form have descended into chaos.

A Walking Plague. Time has long forgotten what Abaddon looked like as a celestial being before the earth took shape. The monstrous form that now serves as Lilith's bodyguard is something from beyond the realm of nightmares. When Abaddon is focused and at the height of his power, his form becomes a corporeal reflection of something almost humanoid, but as he allows the power of wrath to flow through him, he becomes something quite different. When Abaddon is unleashed, he is revealed to be a fiendish swarm of locusts born from the violence of the abyss. He is a walking plague, he kills without conscience, and he is addicted to destruction. Even Lilith fears what might happen if Abaddon was let into the world. As such, she has assigned Abaddon the role of her personal protector and guardian of the Fellowship of the Beast headquarters in the Catacombs of Kadesh. Here Abaddon's locusts hum and buzz with a violence that is only barely kept in check by the remnants of his intellect. While Abaddon is encountered in his swarm form, each of the tiny locust-like creatures buzz with a sound not unlike that of thousands of voices chanting "Abaddon, Abaddon..."
