The Nest

"... A Soul Eater moves into a house, and once it does, it makes what the lore refers to as a Nest. A place that exists outside of time and space. The Nest looks and feels like whatever house the Soul Eater is in ... The Soul Eaters aren't really here or there, but apparently they can muster enough strength to yank their vics' souls out of this world and into their Nest. And then, as soon as the vic's in The Nest, they're outside of our space and time ... Apparently, The Nest messes with their victim's head, shows them things they love, parts of their soul in distress. It keeps the victim's soul vulnerable ... the meat suits in the real world? They wither and die in the real world ... And the Soul Eater, closes up The Nest and moves on to the next house ... the remains of the souls in The Nest? Well, they wither, too, but they stay with the Soul Eater, keeping it fed in lean times, sort of like a cud."
