Here is a list of dark alien entities that my spiritual guides have detected in people who have consulted me or that I´ve worked with. These entities act like earthly demons. They strike unconscious deals with humans, granting them their wishes and after death they take their souls into slavery. The difference with earth demons is that aliens also steal their victims´ soul fragments, piece by piece, until they take their entire souls. Then they walk into these persons´ bodies and live their lives. These entities also place etherical implants which allow them to absorb energy and transmit certain thoughts, feelings, orders, hallucinations, etc. In other words, they run experiments and get energy. They are dark because their planets have deals with dark force entities. This puts them outside of the divine source, which is every being´s source of energy. So they need to steal that energy from light beings. That doesn´t only happen in the incarnation where the deal is made, but in many following incarnations somebody´s higher self sends, according to one´s soul mission. The final goal is to seek help and get a karmic cleansing. The diversity of these creatures is unlimited. They move astrally, i.e. by thought, but some of them also have spacecraft. Some are able to create physical bodies by willing them, others can´t. However, the fact that a being is on this list does not mean that there aren´t similar ones of the same species that are light. The planet of origin of those beings isn´t revealed to me by my spirit guides because it could be dangerous for me. My conscience would go there and since we wage war against them, a link would be established. Several of them live in more than one planet.
