Married into the Wolf Castle My Child Rules Both R

I am a hybrid, rejected by both the werewolf pack and the vampire clan. The day I was carried into the Wolf Keep, my fiancé adjusted my bridal gown. His touch was gentle, his eyes brimming with love. But hidden in his sleeve, my fingers brushed against a Bloodline Seal. Once activated, it would suppress my power entirely, stripping away my ability to fight back and leaving me at their mercy. Standing in the center of the grand wedding hall, I felt the elders’ eyes on me. They weren't looking at a bride; they were sizing up an object. Their plan was simple: use me to breed a pureblood wolf heir, and then discard me.
