He wants to tap into her life force because, she's been celibate for ten years. This is non-consensual because she is a warrior of light.

It sounds like you're crafting a narrative that involves themes of consent, power dynamics, and perhaps a struggle between light and darkness. If you’re developing a story, consider the implications of non-consensual actions—how they affect your characters and the overall message of your tale. In this context, the warrior of light could symbolize purity and strength, making her the target of an antagonist who seeks to exploit her for their own gain. You might explore her journey—how she discovers this threat, her allies in the fight, and ultimately, how she stands her ground against this dark force. You could also dive into the psychological aspects of her celibacy—what it represents for her and how that contrasts with the intentions of the antagonist. This juxtaposition could provide depth to both characters. What direction are you thinking of taking this story? Do you want to focus on action, psychological conflict, or perhaps moral dilemmas?
