The Book of Briars contains four locks which prevent the book from being opened. Each of the book's locks in opened by a key, which is the major hunt that Mountaineers must embark on. The keys are found through fragments, which are magical keywords that unlock portions of the Book of Briar's website. Finding four fragments unlocks a new key. After four fragments are obtained, the Book of Briars initiates a Magimystical Assessment. The assessment involves answering a number of questions which can be answered using the information from the four fragment pieces. After enough recruits have passed the assessment, the key will successfully turn the lock.
