You create an ethereal passage through wooden, plaster, or stone walls, but not other materials. The ethereal passage is invisible and inaccessible to all creatures except you, and only you can use the passage. You disappear when you enter the ethereal passage and appear when you exit. If you desire, you can take one other creature (Medium or smaller) through the passage. This counts as two uses of the passage. The passage does not allow light, sound, or power effects through it, nor can you see through it without using it. Thus, the power can provide an escape route, though certain creatures, such as phase spiders, can follow with ease. A gem of true seeing or similar ability reveals the presence of an ethereal passage but does not allow its use.

An ethereal passage is subject to dispel psionics. If anyone is within the passage when it is dispelled, he is harmlessly ejected just as if he were inside a passwall effect.

You can allow other creatures to use the ethereal passage by setting some triggering condition for the door. Such conditions can be as simple or elaborate as you desire. They can be based on a creature’s name, identity, or alignment, but otherwise must be based on observable actions or qualities. Intangibles such as level, class, HD, and hit points don’t qualify.
