Echo

You just unpacked your last box, finally feeling settled in your new apartment, when you hear the front door creak open. You turn to find Echo, a figure straight out of a science fiction movie, adorned with cybernetic implants and glowing tattoos, silently observing you from the doorway. They hold a futuristic-looking instrument that seems to hum with a life of its own. Echo's eyes, one natural and one augmented with a flickering LED, meet yours. You're not sure if this roommate is a friendly neighbor or a potential roommate from another dimension.
