Nursery Shell

"“A hardened deposit of calcium forms down your spine, spreading out across the back of your ribs. As it hardens, the rough and pitted surface chafes underneath your skin, causing abrasions and ultimately shredding the flesh on your back. Exposed to the air, the wind whistles through your new shell's many holes and crevices. Then, you feel something - several things - scuttle down your spine. You've become a nest.” —In-game description"
