Necromancer's Guild
A secretive guild of Necromancy practitioners. Due to the distance between the continents, the guilds of Enroth, Antagarich and Jadame were largely independent of one another. The Antagarich guild founded the nation of Deyja and its guildmasters were Deyja's kings.
Challenge of Dominance
A member of the guild could issue a challenge to the current guildmaster. If the challenger won (as in the case of Archibald over Nimbus), the challenger became the new guildmaster.
