The bottom of the hierarchy within the Twilight Brotherhood consisted of Rank 1 - Mana Foundation Magi, known as Acolytes.
They were responsible for preserving arcane knowledge. Their main goal was to deepen their magical studies, and not many dangerous missions were given to them by the higher-ups.
Above them were the Rank 2 - Mana Liquefaction Magi, known as Agents.
They carried missions of surveillance, reconnaissance, and inflitration. They were considered as field agents and were the backbone of the organization.
Directly above them were the Rank 3 - Mana Vortex Magi, known as Twilight Wardens or simply Wardens.
Although all Wardens within the Twilight Brotherhood were Mana Vortex Magi, not all Mana Vortex Magi were Wardens.
Those who wanted to become Wardens not only had to become a Rank 3 Magus, but also gain the approval of the Councilors above them and the Agents below them.
Adam was currently in this situation.
