Alternate Advancement Knowledge
There was an age when even the greatest heroes believed that mastery was governed by time. A warrior might learn a devastating technique only to find that its use delayed another. A scholar might uncover two separate secrets of power, yet be forced to treat them as though they were bound to the same rhythm. For generations, such limitations were accepted as immutable laws of advancement.
The deepest students of Alternate Advancement eventually discovered a greater truth: knowledge is not bound by time. Every Alternate Advancement is a lesson learned, a discipline mastered, or a secret made permanently part of the adventurer who possesses it. One truth does not erase another, and invoking one piece of knowledge does not cause every other lesson to be forgotten.
