The unseen guest
Narrator: now with every villain there's an assasin wanting to kill that villain and Zim is no exception to that rule, his assasin goes by the name of kazzan she was trained by dark spirits as a child and can use their ghostly form to hide herself and make her practicaly invisible and can apperate a blade of pure darkness, the power is a source of arcane energy the same as Warren, so as Warren was sneaking around the house he could sense a arcane essense and decided to seek it out, as he got close he could see the arcane outline of Kazzan.
Warren: Halt arcane maiden are you a colleague of Zim's because if you are i will have to teminate you.
Narrator: Kazan turns off her invisiblity and apperates her blade
kazzan: I could say the same to you oh mage of all things gothic
Warren: I am Warren modern necromancer and friend of the hero Archrival.
