The tall man

I found the inspiration for the tall man in charmed. He can absorb worlds/all magick/immortality you name it. He truly is as dangerous as they made him out to be in charmed. "The Tall Man was a powerful demon who was believed to be impossible to be vanquished. His body served as a dimensional portal. The Source of All Evil felt so threatened by him, that he ordered the Seer to forge a magical cage to imprison the Tall Man for all eternity. Due to him being imprisoned for centuries, his true name is unknown." This demon is so powerful I have recreated that cage on the astral until he has a companion.  The cage will go with the companion.
