Guildmaster

Guildmasters wield the ultimate authority within their organization. Within the most notable guilds, the guildmaster is typically long lived and very powerful (a dragon, an angel, etc.). In some guilds like the Thieves Guild and the Assassins Guild, the guildmaster's identity is unknown.

Responsibilities

The guildmaster is responsible for making the broad decisions of a guild, such as whether to open or reinforce a new chapter somewhere, and also deal with political leaders. Additionally, they are usually involved in especially important contracts.
