Puzzles

Puzzles are devices designed and built by members of the Order of Monastics to use both for personal training as well as defense and security. Because of their telepathic abilities, many Monastic Puzzles are designed so that there is no conventional way to reach or manipulative the opening-device for the Puzzle. Only beings with telepathic abilities can "reach" inside to open them from the inside out.
Puzzles are often used to hide information or objects the Monastics don't want other Supernaturals getting their hands on. Puzzles have also be installed in doors to the inner-sanctums of many of the Monastics monasteries, making it difficult to move about a Monastic habitation if one is not telepathic and therefore can't open any of the gates or doors. 
Puzzles can be highly-sophisticated and complex, or deceptively simple. Some Puzzles are easily solved simply by moving a gear or lever within the machine, or activating a hidden latch from within. Others involve moving liquids with one's mind into containers or arranging several items at once into certain formations. The best Puzzles, which only highly advanced telepaths could hope to open, operate on multiple levels, requiring several, simultaneous actions in order to solve.
Puzzles that are meant for defense or secrecy are built to prevent illegal outside manipulation. Attempts to insert tools or devices of any kind usually result in breaking the Puzzle completely, and releasing an acid of some kind which destroys the object within.
