Among the assortment of organized criminals who live in the great city, few command greater fear the Moonbeard Order.
They of course do not call themselves that, but have earned the moniker from their fashion of dying their large beards with lye to produce a distinctive crescent shape running from earlobe to earlobe. This is meant as a taunt for their enemies, for it clearly outlines their throats.
They also wear garb similar to the northern tribesman, carefully tooled leather and showing multiple, colourful glyphs.
They are feared due to the intense discipline that their group maintains, due to their origins as a warrior-sect.
They serve as paid thugs, enforcers and assassins within the city, with the client simply ordering a service from the organization, not hiring an individual. Apart from making the request and providing payment in full in advance, the order completes the assignment themselves.
Their order has many moles through the organizations of the city, and more than a couple of nobles. As such, no organized move has been made against them since their chief activity is directed against other members of the crime world. It is said that their services have been useful for those in power as well, further protecting them from persecution.
Their religion holds that their time in this world is vanishingly brief, and largely unimportant except as training for the Great Battle.
The order is very utilitarian with weapons choice - they simply use the tool needed for the occasion, though not without having trained extensively with it beforehand. Daggers, garrottes, swords, bows, battle axes, polearms, wagons, even siege engines have been used to carry out their contracts.
You find a patch of edible funghi. They taste well and all, no ill effects. UNLESS you consume some beverage, even 3 (three) days after eating it. Then you become really sick with pains, vomiting, all the fancy stuff. As a gift or good meal, it could be a cruel joke or to make sure the heroes spend their time focused on the mission. And the fine soup you had in the inn yesterday could have some in.
(Inspired through a real-world fungus. Was really used to cure alcoholism.)
