This is an extremely complex spell requiring significant preparation before casting. First, an ornate, rune-encrusted stone archway must be built, with an iron door hinged therein, the cost of constructing this being no less than 10,000 gp. The runes follow a prescribed pattern, but the door may be decorated as the designer wills. The spell is then cast, and during the process the wizard must not be interrupted. This infuses the arch (and door) with the proper magics. Included in this casting is a specialized form of the permanency spell. When the spell is finished, the door may then be opened into an extradimensional space of extensive volume: 10 cubic yards per level of the caster, in a simple shape of the caster's choosing. No complex forms may be made; thus, cubes, domes, and other simple, continuous shapes are the only possibilities. The space is featureless and black; not even the edges of its "walls" are visible, although they are certainly solid to the touch. However, since the space is permanent and stable, the wizard can have facilities built within, regardless of the weight brought inside. Note that it does not matter where the arch is set up, in the side of a wall, or even free-standing, it is only accessible from one side, the other being featureless stone. Also, note that other extradimensional spaces may be brought herein; the door will not open for someone carrying such a space, be it a bag of holding, a portable hole, or even a deeppockets spell whose duration has not yet lapsed. The space maintains the last temperature and atmosphere verbally requested by the wizard, the environment shifting instantly, with conditions anywhere between 0 and 120?F, with atmosphere ranging from high-altitude to thick, sea-level, from extremely foggy to pristine, and from muggy to desert-dry. Note that deadly conditions and extreme weather may not be set up herein. Many other spells favourably interact with the Nilspace's make-up; notably unseen servant, magic mouth (reprogrammable in this case), invisibility (on the door), guards and wards (switchable), and others, including Darklight's mysterious manservant. Incorporating such a spell into the fabric of the Nilspace requires an additional hour of casting during the creation of the space, along with another 1,000 gp of craftsmanship on the arch. Another method is to cast the spell to be incorporated with the assistance of certain special components, different for each spell, but uniformly rare or expensive. The incorporated spells are permanent within the nilspace and are usually "user friendly", such as the reprogrammable magic mouth mentioned above; the DM must decide what spells may be treated this way, but no offensive or healing magics will take hold (typically the spells are utilitarian in nature and of low power). Destruction of a nilspace is extremely difficult and requires the equivalent of a wish. The spell was created by the wizard Darklight.
