You may cast this spell only while under the open night sky, which allows you to have a conversation using the stars as your conduit. At the beginning of the spell, you must trace the face of the recipient in the stars, pointing from star to star until you have a clear image in the mind's eye of a constellation in the subject's likeness. You then enter a trance, staring at this new constellation, and your face appears on a constellation above the subject Both you and the subject can speak to the constellations above you, and both will hear clearly as though seated next to one another. The conversation may last as long as there is starlight. Dawn ends the spell. When the conversation begins, you exit the trance and may walk and act normally speaking to the constellation for as long as you like, as long as you maintain concentration on its image. If you go indoors or underground, then spell ends.
If the recipient is not under the stars at the time of casting, or the stars are obscured from him by clouds, fog, or unnatural darkness when the spell begins, you can choose to exit the trance (ending the spell) or remain in the trance. You can remain in the trance until the subject is under the unobscured stars; once the conversation begins, clouds, fog, or unnatural darkness may obscure the stars without it affecting the spell - the light of the constellation continues to shine in the minds of both you and the subject. Naturally, this spell can only be used to communicate with someone on a plane of existence that has a sky containing stars. if you are disturbed during the trance while waiting, you awaken and the spell ends.
Blind creatures cannot be contacted by this spell. The subject must be able to see the constellation for contact to be made, but only a glimpse is necessary. if the subject is under the open stars, his eye is drawn to the constellation; he need not be aware that it is there. if the subject does not wish to be contacted, he may simply refuse to look at the constellation and the spell will end without you ever knowing that the subject has seen it.
You are unaware of our surroundings or he activities of those around you while in the trance. You are defenseless, both physically and mentally - you always fail saving throws while in this state. Once the conversation begins, you may act normally. Anything that happens to your or the subject that disturbs your concentration on the mental image of the constellation ends the spell.
