Ecology

Assassins are not random murderers; they are trained professionals operating under guild contracts, intelligence agencies, or cult networks. Training begins young — often in childhood, in a hidden school — and emphasizes infiltration, poison craft, lockwork, and long-range patience as much as combat skill. A working assassin handles three to six contracts a year, rests between jobs, and maintains a meticulously normal cover identity (a cobbler, a clerk, a sailor). Most belong to a guild that takes a cut of every contract and provides legal protection.

Behaviour

Assassins are observers first. They study the target for days or weeks before acting, mapping routines, identifying weak windows, and never striking without an exit plan. In conversation they are unremarkable — bland accents, forgettable faces, no strong opinions. The personality they show in their cover identity is rehearsed. They take pride in clean kills, dislike collateral damage, and refuse contracts that violate guild rules (children, pregnant women, fellow guild members).

Origin

The assassin's guild model arose in the great trade cities, where merchant houses needed deniable violence and sponsored the first formal academies. Earlier traditions of contract murder existed everywhere, but guild-trained assassins displaced freelancers within a generation by offering reliability, professionalism, and the political cover of an institution that powerful clients respected enough not to cross.
