Ages ago, when the elves were still united as one, the Elf Queen locked away a portion of her power in a magical vault. In hindsight, this may not have been a good idea; in the chaotic 13th Age, it has turned out to be a terrible idea.
Over time, the original elven guardians of the vault’s keys have been stealthily defeated or corrupted; and now the keys to the Elf Queen’s power are hidden in three magical towers—one for each of the three elven peoples—and the elves themselves cannot pierce their defenses.
What to do? Summon heroes, of course! Glory, riches, and power will surely flow to those who answer the Elf Queen’s call . . . or perhaps to those who want her power for their own icons.
