This odd species of Outsider is intended to make an interesting and thought-provoking sort of antagonist, especially for Druids, and a lesson in the balance of nature. People often think of death as bad or even evil; the Tanzu demonstrate that life is never that simplistic. Druids probably spend a lot of time preventing the destruction of wildlife, but they would have to stop the Tanzu’s actions or ecosystems would be damaged and eventually, completely collapse.
