Magicians' Guild
The King's Quest Companion makes mention of another magical organization which various characters are connected to called the Magicians' Guild. The Magicians' Guild is a guild of magicians, enchanters and sorcerers. Manannan and the Enchanter (Sorcerer) were members of the guild. Wandering magicians formed the loose organization, its members are easily recognized by their distinctive black and purple pointed hats decorated with the image of a crescent moon. The guild passes on information about different spells to its members, along with magical gossip. As magicians become powerful enough to be considered sorcerers, necromancers or thamaturgists, the tend to leave the guild, thereby amplifying the notion that the guild is just a collection of amateurs. For whatever reason although Manannan is an extremely powerful wizard, he is still a member of the guild.
The information concerning the Magician's Guild ties together characters such as the Sorcerer from KQ1, the Enchanter from KQ2, and Manannan from KQ3 together as part of the same organization. Abdul Alhazred may even be tied into the group as he wears the crescent moon symbol of the organization on his turban.
