Embriums are flowers from the orchid family. Its therapeutic qualities were actually discovered because of the embrium's exceptional beauty.
The beloved daughter of Lord Ignace Poulenc of Orlais fell victim to a terrible sickness of the lungs, which her healers were unable to cure. Thinking the girl would soon perish, her parents surrounded her bed with brightly colored flowers, hoping that they would bring some warmth and cheer in her last days. Oddly enough, the girl began to recover from the illness, and grew stronger each day. Her parents were baffled, but overjoyed. The healers eventually learned that the fragrance of one of the flowers eased the child's breathing. The flower was an embrium, and later became known as the Salubrious Embrium.
The other variant that has certain magical properties is known as Dark Embrium.
