Thin, faceless, vaguely humanoid, the Child of the Grey is a servant of something beyond the gods - raw nihilism made flesh. Most of the Children were trapped away from the world at its creation, sealed away from reality by the Divine. A spellcaster of appropriate bent or a crack in their prison can occasionally let one or more into the world. They have a fluid shape (but generally stay humanoid - two arms, two legs, and the occasional set of wings), and, upon destruction, explode into a cloud of grey ash that settles to earth. They do not personify death, but rather nonexistence - things destroyed by the Child's annihilation abilities are permanently gone, reduced to a sort of greasy dust that bears not even the mystical memory of what it once was, and is useless for... well.. anything. The Children are not so stupid as to indulge in wanton destruction, however. A single or small group of children will work to free their brethren, hoping to release a wave of nonexistence that will destroy all of reality. To this end, they will often work through cults or other agents of destruction, even coopting some of the followers of evil gods for that purpose. Instinct: To erase existence

• Attack with an ash- or dust-like construct, at any visible range. This construct can appear from any surface.
• Once, when the child is threatened by attack, it may alter reality in a subtle, destructive way to negate that attack for the duration of the conflict. (e.g., arrows no longer fire, a particular sword no longer swings correctly, an environmental hazard is negated or created.)
• Create tentacle construct - the Child can create a long-lasting, independent construct of dust or ash that consists of many tentacles apparently sprouting from the ground, water, or other equivalent source. This is an environmental hazard that can hurt (4dmg), rip away weapons, and more. Corrosion - The Child can annhialate a non-alive object it can touch, reducing it to a fine, grey powder.
• The child may change shape to add advantageous attributes - say, sprout wings, extend claws or reach, or more. Its body seems fluid.
