The Marvinogian was an ancient, seven-headed creature once regarded as one of the most powerful of Babel's eldritch servants. Defeated and imprisoned within an iron box by the spirit Dunamis, the elephantine monstrosity was the secret charge of the Archprelates of the Holy Church of Achaea for centuries. During the the Battle of the Storm in the 6th century AF, Babelonians used a ceremonial necklace called the Torc of the Archprelates to release the creature, who lay waste to the streets of Shallam and the Erisian Pyramid.
Its task finished, Babel drew the fabled Sword of Dunamis from its side. Discharged by its leige, the horror of deep space consigned itself to nothingness, entering the black abyss of chaos to its final rest.
