I know spells that would normally allow travel between or communication with people on different planes of existence, but I haven't been able to do the traveling or make contact. I also can teleport, but I'm unable to do so off of the island. I do know a spell that can allow for the detection of thought, but I don't use it very often, especially since coming here, and I'm unsure if it's similar to what you're describing.
Also, I apologize; my manners are lacking today, it seems. I'm Essek Thelyss and I am also a wizard.
