Oath of Protection

An oath of protection is one in which a powerful individual is sworn to come to the aid of another in a time of great need. One of the most famous of these oaths in mythology is the oath that the Achaean kings swore to Menelaus, husband of Helen. The kings swore to assist Menelaus if anyone ever threatened Helen. When Menelaus called upon the kings to fulfill their oaths, the Trojan War was the result.
An oath of protection requires the swearer to answer a call for aid as quickly as possible. Once the threat has been neutralized, the oath is fulfilled, and there is no further obligation. Failure to answer the call, or even allowing the other party to come to harm, will cause the oath giver to be branded an oathbreaker, and they too suffer the curse of the treacherous.
