Dryad
Native to Dominaria, Rath, Mercadia, Mirrodin, Ravnica, and Innistrad. Dryads are sentient vegetal life forms generated by the force of life within forests. Secretive and mysterious, they are rarely seen on most planes (though they inhabit many). They have a close mental bond with the trees and flora of their native forest, however, and cannot venture far from their homes. On Mercadia, they are the servants of Ramos. On Ravnica they are the primary power in the Selesnya Conclave, the so-called "Cult of Life." The Parun of the guild is a dryad named Mat'Selesnya, whose magic sustains the guild, the Guildpact and the plane itself.
(Rushwood Dryad, Chorus of the Conclave)
