Druidic

Although it is referred to as a language, Druidic is more similar to a secret code. A fundamental skill taught to many who forage, hunt, and other natural vocations, it is generally understood that individual plants have symbolic meanings. These meanings can be relatively simple - such as roses referring to "love" - to complex, and when grouped together, complete messages can be conveyed. To the untrained, these messages appear as only a cluster of plants.
