It's not an inherent trait, it's an upper-tier header for any shaman that hasn't committed to another path. If you're currently playing a shaman, talk to a druid in-game for more information, if you're looking to set a new character in that direction, talk to staff privately and we'll figure things out.
Also, just leaving the website description here for reference, if folks haven't seen it:
Druids: Shamans who draw their power from the natural world sacrifice a closer connection to the Cycle and learn to channel the power of nature through their bodies. While they don't transform into animals like Therians or those cursed with Zoanthropy, Druids do learn to change their form to mirror various aspects of the natural world
