You alert the nearest twenty deep ones or deep one scions (but not deep one hybrids) to your location and interest in communicating. You can’t convey any more specific message than this. The deep ones receive a brief glimpse of your appearance and gain enough familiarity with you to contact you with sending or target you with scrying. They also get a clear enough sense of your location to teleport there with teleport as if they had viewed it once. The deep ones gain no further special ability to travel to you or communicate with you, however.

Typically, deep ones will cautiously learn what they can about you before approaching or otherwise making themselves known. If you appear weak and vulnerable, you might simply be abducted for questioning by their leaders.
