The Four-Winged Unborn Key is a grotesque yet intricately designed artifact, resembling a large, ornate key with a body forged from tarnished silver and adorned with four skeletal wings that appear to be in various stages of decay. The key's bow is shaped like a twisted, fetal figure, giving it an unsettling, unborn appearance. The shaft is etched with cryptic runes and the teeth are jagged, as if broken or grown irregularly, suggesting a dark, organic origin. The entire piece has a slightly luminescent, sickly green hue, with patches of corrosion and what looks like dried blood in the crevices, enhancing its eerie and otherworldly aesthetic.
