The universal planes house a number of worlds that are home to the higher beings and demonic entities aligned to the side of Good or Evil. Within the higher planes you can find the realm of The Elders, the spirits of good souls, and the ever-watchful Powers That Be. The lower planes are home to the demons of old, the souls of the damned, and things much more sinister. Noticeably, the Heavens are heavily traveled by Whitelighters and other Angelic agents. Conversely, the Underworld is the most prominent of the lower planes and is frequented by many demons and other evil beings.
