The Inquest Liquidators
The liquidators are a special division of the Inquest. While its members are middling in rank, usually on the same level as higher level researchers under overseers, they have a very special purpose: unlike assassins, they specifically focus on members of the Inquest that have abandoned their post, typically at the behest of the Ethics Committee.
Of course, the liquidators aren't just called in for any breech of contract, no. Liquidators focus their attention on deserters who have done something particularly egregious, such as killing other faculty members or giving away Inquest secrets on their departure.
A liquidator's job is listed simply as "providing a pink slip," which really is alleviating a deserter of their life. They are trained killers, good at their jobs, and both respected and feared in the megakrewe.
Led by the bitterly cold Manager Vroqq, he often works in lockstep with Miyya of the Ethics Committee.
