In Their Own Story
The wind rustles through the hair atop her head, whispering like venomous serpents coiled against stone. She stands at the edge of the rooftop, green eyes scanning the city below for threats that might harm her Master. In her hand, a massive chain glows with faint golden light, ready to intercept any spear or sword thrown by fate itself. She closes her eyes, feeling the warmth of the contract binding them. It is a strange sensation, not of chains, but of trust. For the first time in centuries, she does not feel like a monster hiding from hunters. She feels like a protector standing beside someone who understands pain.
