🌶️ as far as i can tell: accidentally. you stumble onto the signs, the haunting symbols, the otherworldly smell of what you can only describe as home. the days as your shadow shifts and garbles, what you've always seen when you focus on it but something else, terrible and comfortable, at the edge of your vision. that other lingers a moment longer every time you notice it.
the realization that you're losing connection to what has been prescribed to you as humanity, and eventually finding solace in it.
and then one night, when your shadow no longer hides its horns and fangs from you, the walls melt. pure night floods you, carrying you away to a home never before seen. where the sigils and letters of living creation all around you narrate back the struggled life you thought you wanted, but now find only rejection for. what emerges from that gentle deluge is the monster you're searching for, one who finally found their place in the world.
.... well that, or if you don't mind a bit of rubber to your demonicness, i can drop by and help skip that entire slow realization process. you might even get to keep your soul!
(i do apologize if this doesn't make much sense. we've been awake for way too long after way too little sleep, and i mostly explained by what my emotions told me to)
