Knowledgelock is a Casterwill spell that transforms the information in a library and seals it in a Cypherdex crystal.
Focauld Casterwill used this spell to transform all the knowledge of the Casterwill Library into a Cypherdex crystal so that the family's secrets would be unable to fall into the hands of the Blood Spiral. The crystal subsequently fell onto the floor, falling into Kiel's possession before being reclaimed by Lok Lambert.
