Litharge is a form of metal that is created as a byproduct resulting from the mutual destruction caused when one of the elemental Kas comes into contact with Orichalka. Litharge has two unique properties. The first is that it blocks Ka in Ka-Vision. Ka generated by people or objects can be hidden behind Litharge. For this reason, secret societies often hide Orichalka weapons in Litharge cases or scabbards to that Nephilim cannot detect the deadly weapons.
The second property of Litharge is its use in creating a Stasis. While the overall stasis can be made of many materials, it must contain a certain amount of Litharge. Litharge is what allows the stasis to bind together a Nephilim’s Ka.
