Members of the Black Lily are usually natives to whatever planet they are based on, chosen because they are willing to help offworlders in spite of fear or prejudice. An existing member of the order will then contact them and ask if they'd be willing to help in the future. The Black Lily utilizes a variety of codes, passwords and message systems. The most common sign is a drawing of a black lily; seven petals around a three-sectioned center. Most members have at least one living plant around their home as well.
