Caul (WTO)

When a Wraith dies, they enter the underworld covered in a plasmic cocoon called a Caul. The caul keeps the wraith docile until it is removed; while the caul is present, the enfant is in a placid, dreamlike state and generally unaware of their surroundings.

Most enfants keep their cauls on until another wraith, a reaper removes them. It is very rare for a wraith to remove his caul on his own, although it is possible. The wraith of Yu Huang apparently never had a caul, but that is the only known case of that happening.

The caul introduces a distinct advantage for the reaper, and unscrupulous reapers may keep an enfant covered until the most advantageous moment. A cauled wraith can be soulforged, moliated or otherwise modified without trouble, making extreme abuse easily possible.
