Thenta Makur
From The Babylon Project
The Thenta Makur are an assassin's guild in the Narn Regime. They leave their "calling card" with a "death blossom" - a black flower - by their intended target as a notice that the victim will soon die.
They are a principled band in that they always follow through with a death commission, which is why they are less likely to except a bribe because that would be betraying a commission, and if someone did dare the organization would find and kill that individual.
G'Kar was targeted by Tu'Pari, a Narn hired by G'Kar's bitter enemy, Councilor Du'Rog.[1]
It is not known whether they operate outside the Narn Regime and accept commissions from non-Narns, but given the nature of such organizations it is highly likely.
