Treefolk
Native to Dominaria, Rath, and Lorwyn. Treefolk are sentient creatures which resemble trees both physically and biologically. They are normally quiet, and slow and lumbering if they move at all, but are quick and relentless in the defense of their forests. They are most often cast as the guardians of a forest's ecology and harmony. In Lorwyn, treefolk start as regular trees, while a few of these will undergo an event called "The Rising," which will transform them into a treefolk. Because of their hermetic nature, few Treefolk have had any major impact on Dominaria's history. Yavimaya's Nemata, Grove Guardian led an army of Magnigoth Treefolk after the escaped dragon, Rith, during the Phyrexian Invasion and later joined the war when Yavimaya itself transplanted to the Phyrexian stronghold on Urborg. The treefolk of Lorwyn take a more active role in society, seeing themselves as defenders of the status quo. In Shadowmoor, many treefolk are infected with an orange-colored fungus called the Canker.
