In past presentations of the Dragonlance setting, several of DUNGEONS & DRAGON's modern spellcasting classes didn't exist. To accommodate these classes, the group known as the Wizards of High Sorcery has evolved into the Mages of High Sorcery. The group's distinct orders and signature robes remain, but the organization now accepts members from a broad range of spellcasting traditions. Members who find their magic influenced by the phases of Krynn's moons also remain part of the group, largely represented by sorcerers with the Lunar Magic subclass.
