Hail to the king baby
All my intel comes from verified and highly trusted , as well as research in the field. I investigate every lead, analyzing every bit of data with the eye of a hawk. I comb out all the bullshit so that only the facts remain.
Research is still being conducted regarding that. the Grays are a likely answer, given their behavior and known interests, but I have another hypothesis: the species commonly referred to as the 'Dogmen'. According to certain reports, they have been known to appear with 'lights' in the sky. At the very least, they are one forces seeking to use humanity.
What about the demons from hell?
