Oath of the Ancients

The Oath of the Ancients was one of the sacred vows that paladins could choose to take when they reached a milestone in their journey of faith. When they dedicated themselves to the tenets of this oath, they also were granted access to a set of spells at no cost (they could cast them at any time without having to prepare them in advance).
