The House of Lammasu, also known by their modern sobriquet Defilers, are the former angels of God who inspired and searched for truth, beauty, and inner power in Demon: The Fallen. Inspiring the others to war, the Defilers were used for morale and healing spiritual wounds. When they fell, were cast into the Abyss, and then escaped, the Defilers became focused on continuing to influence humans, but not always for pure purposes.
The Lammasu were the third House to present themselves before Adam and Eve during the Fall; they gave them the gift of water to drink. The curse placed by Michael upon the Lammasu was a twist on their original purpose. Humanity would continue to grow and learn, but become so involved with seeking pleasure that all that the Lammasu hoped to teach them would become lost among that pursuit.
