Sacred Oath: Oath of Knowledge (Patreon)

The Oath of Knowledge is sworn to the idles of  safeguarding magic, the protection of common  folk against tyranny, the conservation of history  and information. Sometimes called arcana  seekers, preservers, inquisitors, or arcane  sentinels. Paladins who follow the oath of  knowledge stop at nothing to end the abuse of  magic after studying and perhaps witnessing the  devastation unchecked magic can cause. Many  paladins of this oath usually join the ranks of  organizations like Candle Keep or the Harpers.
