Demiplane Seed (Alteration) Level: 8 Range: Touch Components: S,M,V Casting Time: Special Duration: Permanent Area or Effect: Special Saving Throw: None ## The Planewalker's Handbook High-level prime mages — especially those who grow bored of their home worlds — often seek this spell. Essentially, it creates a tiny pocket dimension within the Ethereal called a demiplane. The demiplanes created by this spell are very small, very minor planes unlike the major Demiplanes of Shadow, Time, or Dread. Not surprisingly, this spell must be cast while on the Ethereal. The actual casting only takes 1 round, but lengthy preparations are required before this can take place — the demiplane seed itself must be created. To start with, the wizard needs a single flawless gemstone worth at least 1,000 gp. Every day, for 100 consecutive days, the gemstone must be enchanted with the following spells: [[Enchant an Item]], [[Distance Distortion]], and [[Rope Trick]]. At the end of the 100 days, it must be treated with [[Oil of Etherealness]] or a priest must be available to cast [[Extradimensional Pocket]]. At this time, only the wizard who has been preparing the seed can handle it, and she must take it into the Deep Ethereal and cast the demiplane seed spell. As the magic touches the prepared gem, the seed grows into an actual demiplane 10 feet in radius for every level of the caster. The demiplane grows slowly, enlarging only 1 foot in radius per day. Once it reaches its maximum size (as determined by the caster's level), it doesn't stop growing, but its growth rate decreases dramatically to only  1⁄2-inch radius per week (just over 2 feet per year total). The environment within the demiplane must be determined at the time of casting, but it can be whatever the caster desires (although no environmental effect within the plane can duplicate effects greater than those of 3rd-level spells), as long as the DM approves. Factors such as solid ground, air, water, and temperature must be determined by the caster. This spell cannot create life, nor can it create construction such as buildings, roads, wells, dungeons, and so on. These things must be added by the wizard in some other manner should she so desire. Because of this spell, the Deep Ethereal is full of secluded little demiplane fortresses of wizards - most of whom are there because they want to be left alone, so travelers should be wary of "dropping in." ## A Guide to the Ethereal Plane High-level prime mages-especially those who grow bored of their home worlds or those with a special interest in the Ethereal Plane-often learn this spell. Essentially, demiplane seed creates a tiny pocket dimension within the Deep Ethereal called a demiplane. Demiplanes created by this spell are very small, very minor planes, unlike the major Demiplanes of Shadow, Time, or Dread. Not surprisingly, this spell must be cast while in the Deep Ethereal. The actual casting only takes 1 round, but lengthy preparations are required beforehand, as the caster must fashion the demiplane seed itself. Initially, the wizard requires a single flawless gemstone worth at least 1,000 gp. Every day, for 100 consecutive days, the mage must enchant the gemstone with the following spells: [[Enchant an Item]], [[Distance Distortion]], and [[Rope Trick]]. Following the 100th day of casting, the mage must treat the potential seed with [[Oil of Etherealness]] or cast [[Lesser Etherealness]] or [[Greater Etherealness]] upon it (or a priest must cast [[Extradimensional Pocket]] upon it). Now the wizard must personally take the seed into the Deep Ethereal (if not already there) and cast demiplane seed upon it; no other being may handle the seed without destroying the previous enchantment. Upon completion of the spell, the seed sprouts in the Deep, growing into a demiplane. At first, the demiplane grows 1 foot in radius per day, to an initial maximum radius of 10 feet for every level of the caster, as the fledgling plane rapidly draws substance from surrounding ethereal vapors and protomatter. Once the new demiplane reaches its maximum size (as determined by the caster's level), it doesn't really stop growing, but its growth rate decreases dramatically to only  1⁄2-inch radius per week (just over 2 feet per year). The caster can create whatever environment he wishes for the demiplane (as long as the environmental affect doesn't duplicate spells greater than 3rd level); he must make this choice at the time of the spell's casting. This spell cannot create life, nor can it create construction such as buildings, roads, wells, dungeons, and so forth; such particulars must be introduced to the demiplane in some other fashion. All demiplanes created by demiplane seed adjoin the Border Ethereal-although the demiplane's environment may affect conditions in that area of the Border Ethereal. The Deep Ethereal contains myriad wizard-infested demiplane-fortresses because of demiplane seed. Most of these demiplanes serve as retreats for the mighty and exist because their owners want to be left alone, so travelers should be wary of "dropping in." Very Rare
