A biologue is a device or machine that uses living organisms to provide its functions. They are grown by viscautorists and fulfill a variety of functions. Biologues of all kinds appear throughout the series.
Like any living organism, some biologues need to be sustained and are fed specialized "food". Some, like the sthenicon, are considered exitious (pronounced "eck-zi-shoos") or ruinous when they are permitted to grow unchecked, which can have adverse consequences for the user.
