She wants to make him her servant

"I require a servant in my lair," Helga said walking while still holding him in the air with her magic.

Kazex kept struggling to try and get out of her magical grip to no avail. "What makes you think I'm gonna work for you, bitch?"

Helga laughed looking back at him. "You make it like you have a choice!"

Soon enough she had him in her lair which was a stone tower on the mountainside. She then placed a leather collar with magic runes on his neck and placed him down on the ground. Once she released him from her magical grasp, he thought of escaping but felt something keeping him from doing so.

Helga smirked at him. "That collar will keep you from running or trying anything. It keeps you from leaving the tower or harming me. But I can harm you so you better do what I tell you."
