The School of Hidden Wisdom stood alone as the sole dueling academy that weathered the storms of both the Clone Wars and the subsequent ascent of Emperor Palpatine to power. Founded on Baltimn by Ephaan Kenzon, this institution became a sanctuary for numerous Jedi who managed to escape the horrors of the Great Jedi Purge.
The academy's operations ceased when a selection of Ephaan's pupils gained admission into Luke Skywalker's Jedi Praxeum.
