Corridor

A pair of shadowy doorways opens at two points you can see within range, and an illusory corridor is formed between them. The doorways are parallel 10x10-ft. squares, and the corridor is a straight line from one door to the other. The corridor can be formed over gaps, through walls, at any angle, or suspended in air, as long as both ends are created in points you can see within range. Regardless of the corridor's orientation, gravity inside the corridor remains directed towards its floor. In addition, when you cast this spell, you can choose if the corridor's internal length is half, equal to, or twice the external distance between the doorways.

The corridor is filled with magical dim light. This dim light is unaffected by darkvision, and nonmagical light can't illuminate it.

A creature can enter or exit the corridor only through one of the doorways. The corridor and everything in it cannot be seen or affected from outside the corridor, except through one of the doorways. Likewise, a creature inside the corridor cannot see or affect anything outside, except through one of the doorways. For all intents and purposes, the corridor is treated as an extradimensional space, except that a creature with truesight can see through the walls of the corridor from within or without, seeing the corridor and anything in it superimposed as a transparent image between the two doorways.

When the spell ends, any creatures or objects inside the corridor appear in the nearest unoccupied space.

At Higher Levels. When you cast this spell using a spell slot of 8th level or higher, the casting time is 1 action.
