Life, Death
Despite Zemos moving out of the wasteland, his followers continued to try to revive the world tree. Furthermore, Zemos kept advancing his research and developing new methods to increase its growth. As the order could not allow this, they decided to take the final step of removing him from the material plane. When he refused, it ended in a battle with a god without followers in which Zemos was killed.
As the attempts to revive Li'minar continued, the Holy Order of Druids were forced to act on it before all of E'ath would be destroyed. At first, they tried to convince him, but when this failed they were forced to physically remove him from the efforts. This too was resisted and it escalated to a battle between the follower-less god and the archdruid. The battle lasted several hours but in the end, Zemos was wounded beyond his divine powers and passed. The archdruid, however, was similarly wounded beyond magical healing and became crippled for the rest of his life. The death of Zemos had multiple other consequences, however. Chief among these was that his divine essence spread across the land where he was killed. This essence could not be absorbed into the land and twisted it beyond recognition. What had before been rolling grass plains was now a twisted shadowy realm that was unwelcome to all life.
