Athulak

The demon Athulak is described as having stalked the dark forests near the great river (Amazonas) for centuries. A demon in human form, he is immune to the weapons wielding by his savage subjects, and sustained by the fear and terror he created from their passions. Athulak can twist inconsequential human desire into cataclysmic harm.

History
His essence was imprisoned in a stone by a powerful woman who could manipulate the elements. After Athulak was trapped, she buried the stone. The symbolic order inherent in the shape and design strengthened the power of the woman's binding spell.

Stephen Tremaine, who was running for congress, got into the possession of the spirit stone from a tribe that inhabited the central amazon regions three thousand years ago. Unknowing that this stone trapped the essence of Athulak he released the demon.

He was banished by Prue Halliwell and Piper Halliwell.

Magical Abilities
Athulak can adjust his molecular density, he can turn himself into a very sharp, very lethal, invisible sword. He can also enhance magical powers if this would suit his purposes.
