The Incorruptible Republic of the Immortal Library of the Grand Architect (The Incorruptible Library, The Immortal Library, or simply The Library, for short) is, to [ quote] [[Chronology - Volume #|✣ ]] Ardsley Wooster, "..an autonomous government which claims a large section of underground Paris off the Black Market. They lend out any book to anybody. Many people find this irresponsible." The Library also has in residence a population of over-sized cats led by a human Catmaster, which can be assembled into armor-clad clowders and dispatched on raiding expeditions against surrounding fiefdoms.
