We do. A new Queen can be chosen only when the full moon and the summer solstice coincide. The current Queen travels to the appointed place and selects one of the specially grown pods, and once selected, that pod will be filled with magic and bloom in the moonlight, when the full moon is at its zenith. That magic passes the Life of the Forest into the new Queen, whoever she might be. Though, I'm not certain exactly how the new Queen, or the pod itself, is really determined.

Apparently it's "all about the feeling."
