The night was dark as the moon shined down upon her. Blood-red hair flowed in her wake as she flew through the streets of Sunnydale towards the source of the chaos magic. One might of called her a glorious avenger as she passed; if one did not know her thoughts.
The Darkness called to her. She could feel the chaotic energy swelling and falling in the town beneath her. The screams, the anarchy, the delicious insanity of it all caressed the primal chaos magic within her blood; her very soul.
This was not her body. The spell had woven itself around her as much as any of the 'innocents' below; torn her from her form to this shell. It did not matter. This form was younger, Sapien but still potent, still powerful even if her host did not yet know it. Their powers were one now and boosted ten fold again by the deep reservoirs of mystical energy swirling beneath this forsaken town.
And soon, she would be more powerful still. She would find the worshipper of Janus and show him what a true Chaos Mage could do. He would beg to worship her, of course. She would take his power and make it her own. His power, added to the power of Chthon and that of the young Sapien who she had possesed, would make her invincible.
Finally, the world would be as her father always dreamt for it to be. She would sweep aside the fascists, the racists and their corrupt Sapien governments. Her children would live again.
Long Live the House of M!
