Manual of the Planes

even if prisoners escape, they’re still on the EtherealPlane, where travel is slow, easily spotted, and sometimesblocked by ethereal solids.As with any portal, each ethereal curtain can have itsown properties. In general such curtains are one-wayportals, although there are exceptions (see the etherealtapestry magic item below).As with the color pools of the Astral Plane, etherealcurtains have their own colors. The D&D cosmology usesthe table below, but you can create your own if you like.The color schemes of ethereal curtains and astral colorpools don’t need to match.Table 5–4: Random Ethereal Curtains for the D&DCosmologyd% Plane Color01–05 Heroic Domains of Ysgard Purple06–10 Ever-Changing Chaos of Limbo Swirling black11–15 Windswept Depths of Pandemonium Crimson16–20 Infinite Layers of the Abyss Swirling red21–25 Tarterian Depths of Carceri Gray-green26–30 Gray Waste of Hades Dark red31–35 Bleak Eternity of Gehenna Bright red36–40 Nine Hells of Baator Red and black41–45 Infernal Battlefield of Acheron Metallic red46–50 Clockwork Nirvana of Mechanus White51–55 Peaceable Kingdoms of Arcadia Pale yellow56–60 Seven Mounting Heavens of Celestia Brilliant yellow61–65 Twin Paradises of Bytopia Dark yellow66–70 Blessed Fields of Elysium Dark green71–75 Wilderness of the Beastlands Emerald green76–80 Olympian Glades of Arborea Bright blue81–89 Concordant Domain Brownof the Outlands90–95 Material Plane Metallic silver96–97 Astral Plane Swirling gray98–99 Elemental or Energy Plane; make a second d% roll01–20 Elemental Plane of Fire Flickering green21–40 Elemental Plane of Earth Flickering gray41–60 Elemental Plane of Water Flickering blue61–80 Elemental Plane of Air Flickering white81–90 Positive Energy Plane Shining white91–100 Negative Energy Plane Glossy black99–100 Demiplane of the DM’s choice Any other colorEther CyclonesAkin to the psychic storms of the Astral Plane, ethercyclones are pressure centers of magical force that roilthrough the Ethereal Plane. They brew up out of nowhereand pose a hazard to ethereal travelers in the area. Theyare usually as temporary as thunderstorms on the MaterialPlane, but sometimes a more permanent ether cyclonecan develop, lasting for years or even centuries.To those on the Material Plane, the ether cyclone hasno effect beyond a shiver down one’s spine or strangebehavior from nearby animals. But on the EtherealPlane, the ether cyclone is an incredibly strong wind.Clothing, hair, and unattended objects are blownabout, and eventually a traveler is uprooted and spunthrough the Ethereal Plane to an unknown fate.The rising winds of a typical ether cyclone provide1d10 rounds of warning before the cyclone reaches fullEtherealCurtainsCelestiaBytopiaElysiumThe BeastlandsArboreaYsgardLimboPandemoniumThe AbyssCarceriThe Gray WasteGehennaThe Nine HellsAcheronMechanusArcadiaThe OutlandsMaterial PlaneAstral PlaneElemental Plane of FireElemental Plane of EarthElemental Plane of WaterElemental Plane of AirPositive Energy PlaneNegative Energy PlaneDemiplanes (Varies)CHAPTER 5:THE TRANSITIVEPLANES57
