Otherness
The Otherness is a malevolent force present in several of the novels by F. Paul Wilson. From the human perspective, the Otherness is evil – greater in scope than Satan and similar high agents of evil, and possibly the inspiration for such entities. In concept, the Otherness bears more than a passing similarity to the entities of the noosphere. The Otherness is engaged in battle with a force known as the Ally for control over existence. Bear in mind that while the Otherness is inimical to human life, the Ally is not benevolent to humanity. The Ally may utilize humans as tools, but it does not oppose the Otherness for the benefit of humanity. On Earth, both the Otherness and the Ally use varying types of champions to further their respective goals. On Earth, the primary champion of the Otherness is Rasalom. Rasalom is older than human civilization as we know it, coming from the mythic First Age, a time before recorded history when magic was commonplace. A powerful creature who may have been human at one point, Rasalom is featured several of Wilson's novels, including The Keep, Reborn, Reprisal, Nightworld, and the Repairman Jack novels Conspiracies, Gateways, Harbingers, Bloodline, By The Sword, and Ground Zero. Rasalom is typically depicted as male, but he is capable of changing his appearance, including his apparent gender. He favors using anagrams of his name, such as Molasar, Sara Lom, Rafe Losmara, etc.

Alastair Reid:
Children are entitled to their otherness, as anyone is and when we reach them, as we sometimes do, it is generally on a point of sheer delight, to us so astonishing, but to them so natural.
Erik Pevernagie:
How can we reconcile " individuality " and " otherness ". How do we bring together two dialectic poles: 'me' and the 'other'. Building up one's " personality " is crucial and consequently self-esteem is required. By listening to the others, by assessing one's life experience, by acknowledging self-regard and amour-propre, open-mindedness can grow generously. Being sensitive to the others, helps to move forward, opens horizons, increases receptiveness and dignity. (" I am on my own side, but I can listen")
