Schemes of the Lich King
Horizon, City of Wonders
Horizon is a magical city heavily influenced by the Archmage. It holds unparalleled libraries of arcane lore, wizards busy with mysterious tasks, rival arcane guilds competing in all ways, and, of course, many opportunities for some wizards to be recognized as exceptional individuals who can accomplish what the other wizards cannot. Of course, it is also home to the prestigious, and sanctioned, Imperial School of Wizardry.
While Concord has the high towers of the elves, Horizon depends much more on flying buildings and floating force ramps. Such constructs are probably a creation of the Archmage, and possibly channel tremendous magical energy originally harnessed
by the Wizard King.
