I was fighting The Lich with my brother Jake, when I put my sword on his shoulder and he began to scream and a green mist surrounded him

What the hell....where is he?

I mumbled in frustration as I pushed the mist away from my face, when the mist vanished and revealed a girl on the ground with my back on her shoulder

What?! The Lich became a woman?!

I said with surprise still without approaching the girl
