Gardener
Gardeners are the elite assassins of the Consultant Guild. They are one of 5 branches of the guild.
Weaponry
Each Gardener can be identified by the pair of "Shears" they wear on a belt around their hip. The Shears are a pair of ancient bronze blades dating back to the Liberation of Asylum that have been handed down from generation to generation of Gardeners, slowly gathering intent to become some of the most powerful artifacts of the empire.
the best examples of this are Shera's shears. They have become some of the greatest weapons on the planet not just because they were invested by The Emperor and Lucan, but also because they gained massive amounts of intent from hundreds of years of killing.
Training
All Gardeners recieve a majority of their training(excluding Lucan, Shera, and Meia) at a place called the Garden. Unlike what you would believe the Garden is not an actual garden but instead is a massive underground chamber filled with various recreated buildings from across the Empire. As you would expect it is there that they learn to kill people.
