The precise nature of the needs and motivations of the Others has been a concern primarily taken up by those in the circles of occult knowledge prior to the present age, but a thing unconscionable in earlier times has transpired with the advent of the internet and related forms of storing, communicating and accessing knowledge. Now, members of the occult community and all of the interlinked secret societies that represent and collect us, are able to interact and discuss openly these sorts of topics with people from all walks of life without fear of any sort of retribution. Much of the reason for occult things being occult (secret) in the first place is the fact that for much of human history, the really critical and important types of information have been deadly to possess and dangerous to seek.
As a case in point: Humanity is not the highest form of life on the planet.
This is actually pretty obvious, but there are significant limitations present in mundane thinking that makes this a difficult pill to swallow. But stop and think about it for a moment: How many epochs have transpired since this world first brought forth life? And how many ages went by unnoticed by man or woman or any creature at all properly called human? Earth is old, my friends, and the cosmos far older, and time has a good deal more wick to burn before the gradual slowing down and dwindling away of the original and most critical sparks of creation. Lovecraft's works may in the end prove more prescient than horrific, and the human need for knowledge and understanding may take us into much darker corners than we yet realize.
A good example of this is Slender Man, created for gaming purposes and as an internet-based phenomenon. But he is drawn from the mythos surrounding Shadow People, a very frequently reported paranormal - or simply other - experience. Shadow People even have specific identities as well, including one in particular that appears as the silhouette of a man wearing a hat and what appears to be a duster or long trench coat. It sounds like the stuff of good horror fiction - and perhaps it is - but for those who have experienced the phenomena associated with Shadow People, this is a very real and very terrifying thing.
We often deride the past and take earlier eras to task for their foolishness and superstition, but this is perhaps in part because we would like to forget what the ancients did for us. We would not have gotten to where we are today without the mysticism, shibboleths and faith of our forebearers. Their supposedly imaginary realities and fallacies have led to science sufficient to land human beings on the moon, and a sophisticated series of robots on Mars. Would there be chemistry without there having been alchemy, or astronomy without there first having been astrology? And could psychology benefit a world in which there had not first been the power of faith, the desperate hope of divine intervention, and the mystic wondering of the philosophers? It was the dreamers and the creators who came first, and the bean-counters who wandered along later to make a thorough mess of things. The purpose of all this science is simple: It takes the magic out of things. The only problem is, many things refuse to stop producing magic and others just ignore the scientists and their findings entirely.
There are many places with magical, mystical significance, and a great many markers have been erected since ancient times to commemorate events and to increase the spiritual value of such geographically encoded meanings and messages. This is the precise way in which theories of ley lines came about, and how so many theorists and speculative scholars around the world and throughout time have come to conclude that another race of beings or another collection of forces influences the course of this world and the history of our species, virtually without our conscious and collective awareness. The chosen few are given to experience the presence of the gods, and to have knowledge of their goings and comings.
The problem is - as Vallee and Tonnies so often demonstrated - the others are still very much with us. Campbell and Jung before him made much of this; human experience is spiritual experience except for when we work very hard for it not to be. In a real sense, this is what the organization and design of the modern, technologically-dependent Western world is all about. We spend most of our time focusing on things of our own agency and making, certain that nothing else matters. We obsess about 401K and stock reports, tracking figures, job performance data and diagnostics. We worry about how lines of code are impacted by interface with rogue lines of code, only rarely fully admitting to ourselves that we have created a collective artificial intelligence and populated it with "viruses" that mimic - and therefore are in many ways the same as - living beings. We pay close attention to television shows that reflect our own baser nature and our desperate need for fame, validation and wealth back at us. By doing these things - stressing about jobs, relationships, politics, research, entertainment and religion - we manage to avoid entirely any personalized spiritual experiences that might cause or permit the intrusion of the Others into our mundane existences. We are safe from the Fae, who after all only interact with those few mortals who bother to take note of them.
Grinning Man or the Raven Mockers. And there are accounts from not so long ago of creatures or entities capable of destroying human life. The Bell Witch comes immediately to mind as an Other of considerable power - although not, admittedly, in the face of a powerful personality like Andrew Jackson.
It is by these mechanisms that we do not have a Bigfoot body on display and we do not have regular psychic communication with the beyond as an option through our internet browsers. This is why the UFO phenomena are no closer to resolution, the Loch Ness Monster has not been found, and wizardry is not a government-regulated industry (and we wizards like to keep it that way). Just as a skeptic might argue that only fools believe these are valid events, the rational person recognizes that the skeptic is foolish and fearful enough to discard millions of reports of the unknown, the bizarre and the out of place. At least one or two of the stories told will have some weird truth at the center. Statistical reality alone suggests that a certain percentage of bizarre reports relates to an actual event that entails utterly unknown or at least unexpected factors. These are the works of the Others.
