The sound you hear is the whisper of the Worldsoul bring you together with all of Selesnya. You mission is only to spread the wisdom of Selesnya so all beings may share in the Conclave's burgeoning song. Our power is from our numbers, and from our numbers you will draw strength - strength to fight those who would destroy the sublime order of nature we champion.
As a new guild member you will find that all of Selesnya is at your command. Leylines will yeild their bounty so you may call on not only our animal allies but massive elemental forces to aid in your mission. Our revered guildmaster Trostani bestows her abundance on you and celebrates your part in the joyous work of our guild.
May you forever dwell within the Worldsoul.
--Molander, Archdruid of the Conclave
