Oath of Sacrifice

The Oath of Sacrifice calls to Paladins that are willing to give up everything to protect others. Paladins who dedicate themselves to this oath believe that any cost is a fair price to pay if it means aiding those that require it and the defense of others at the cost ones life is the greatest honor a person can achieve. Unafraid of dying and generous to a near fault these paladins refuse to tolerate any who prey on the helpless and down trodden facing down a greedy lord with the same ferocity they would towards a demon. The paladins that follow this path are referred to as Defenders, War Guards, and Knights of Sacrifice.
These Paladins hold selflessness and charity above all else willing to offer coin and aid to any that need it. These warriors believe that a helping hand should always be offered and no-one in need should ever be turned away. Many try to take advantage of these Paladins thinking them foolish and gullible only to find themselves mistaken when said paladins are holding them at sword point. None question the integrity and honor of these warriors in fact many hold them in high regard and respect them without question.

Sacrifice is an honor – To give all of ones self in the defense of others is the greatest honor a warrior can have, the act of sacrifice is a noble one and should be treated with the greatest respect.
