The Deep Wilds was a plane in the Astral Sea that was home to nature deities including Silvanus, Mielikki, Auril, Malar and Umberlee. Silvanus ruled the plane and the other deities who dwelled in the Deep Wilds served him. Every type of environment found on Toril was also found in the Deep Wilds although the version found in the Deep Wilds was much more extreme than that on Toril.
