This nightcap was procured at the nameless Goblin Market where it was gained for an unknown but likely unholy price. The cap pulls those the dreamer concentrates on in the dreamer's dreams and makes them UTTERLY vulnerable. In other words, the person is a lucid dreamer while their victims can do nothing. Furthermore, the user has an effective Wyrd of 5 while using the cap.
This appears to normally appear as a simple ratty old nightcap.
Mien: The cap becomes the blue black of midnight, with luminous moons and bright sparkling stars upon or within the fabric.
Drawback: When one uses the cap, a victim may be summoned, but they are stuck there until a way out is found.
Catch: When used "improperly", the user must ALWAYS wear the cap while unconscious or asleep, lest the tables be turned, they weak as a babe, while their former victims become the masters!
