Planar Chamber

When you cast this spell, you choose a command word and trace a square up to 2m to a side onto a solid surface. For the duration, when you speak the command word, a portal appears where you drew the shape. The portal leads to The Apparatus if cast as an Integral spell, to The Dreaming if cast as a Strange Spell, or to The Umbral Halls if cast as a Shadow spell. Speaking the command word again will close the portal.

The interior space is a cube, Power meters to a side. The interior appearance depends on the nature of the spell. The Apparatus produces an interior with shifting Truemetal gears and glowing Truecrystal furnishings. The Dreaming creates a dreamscape structure to your specifications. The Umbral Halls create a semi-real shadow realm much like the space outside of the portal. The interior of the space is indestructible.

Instead of opening a portal to the associated realm, this version of the spell pulls a structure from into the current realm. The size of the summoned structure can fill a cube, up to 100m to a side.
