Like every quild, MoD is based on a certain hierarchy, it is to be reaspected at all times, and never to be expoited.
In ascending order:
The rank hierarchy of MoD is based on dualism. For a merchant of death there are 2 parallel paths to choose/bee chosen to follow.
After the initiation in the guild, a new member becomes a trainee during this phase he is given both tasks typical to agents and defenders. Based on the way he completes them (taking his own wishes in account as well) he is then assigned either to the Agents, or to the Defenders.
Agents Agents are the guilds eyes and ears. They gather information about specific regions, persons or organizations and write reports on their findings. Agents strive for ever growing knowledge and wisdom, they excel in knowledge of history, politics and other aspects of Azeroth and beyond.
Defenders in privilege, defenders are equal to Agents. Defenders seek perfection in armed combat or spellcraft. Their most important duty is, to work together with Agents on assignments. The Defender is no bodyguard of the Agent, he is the expert in tactics and combat, and is essential for every expedition and its covering in a report.
Seeker a senior Agent, who has proven himself in various missions and is given higher authority and more responsible and difficult tasks as well. Together with Guardians, the Seekers oversee and assist their junior colleges.
Guardian an experienced and battle-tested Defender. On missions, he works with the Seeker an together they oversee and assist their junior colleges. Guardians and seekers hold soft power in the guild. They cannot accept, promote or demote members, but disrespecting them will result in disciplinary actions.
Loreseeker Loreseeker is an elder (officer) member of MoD. Together with the Captains, they manage the guild. The oversee guild events, take disciplinary actions and also undertake missions of crucial importance and exceptional difficulity.
Captain Captains, like the Lorerseekers, are elder (officer) members. Together with the Captains, they manage the guild. The oversee guild events, take disciplinary actions and also undertake missions of crucial importance and exceptional difficulity.
Magister/Master-of-Arms The two superiors of the guild. Masters in their own field and equal in privilege. They both are responsible for all guildmembers, but logically, the Magister oversees and leads the Loreseekers->Seekers->Agens and the Master-of-Arms leads the Captains->Guardians->Defenders
