TKW 80: Within the Klingon Empire, there are no written treaties ... This has caused conflicts from time to time in dealing with the Federation, which prefers documentation. KGT 121f.: The idiom bIQ'a'Daq 'oHtaH 'etlh'e' ("The sword is in the ocean") is used to mean that something has ended, that it is impossible to return to a prior condition, just as Kahless and Morath never spoke to each other again. The expression might be used, for example, in reference to a treaty that was just signed, suggesting that a former state of antagonism has ended forever.
