Are any Anunnaki psychics who are interfacing psychically with humanity and deceased Anunnaki spirits resident on Nibiru? Does location matter at all to them for this work?

Yes, there are many psychics on Nibiru who are involved in carrying out these operations. As you know, there is only a small contingent on the earth itself, most are present off-planet on their home base. Because non-local consciousness is not limited by distance, they are just as effective operating from their home planet. As long as they have the information concerning what targets need attention, they can operate from anywhere.
