Angel of Oaths Tennants

Thine has summoned myself, you either search for an oath to guide your life, or are a fool who doesn't know any better. If thou wishes to undertake an oath, myself will grant you powers to uphold your vows. However, if thy breaks the oath, not only shall you lose all power. You will be disgraced by the goddess Elaine and for forbidden from entering her domain upon passing on. Those banned from one deity cannot enter another's domain. Seize this warning with heed.
Yourself shall follow these tenants as much of a necessity as sustenance. As your oath is your sustenance, you shall breath your oath, walk your oath, and live your oath. If thy break any tenant one has dedicated himself to, damnation will await his soul.
One, thy shall dedicate themselves to their oath. No moral, personal grudge, nor convenience is more important than the oath.
Two, thy shall be ready to sacrfice blood and flesh for thine oath. No matter the threat, you will fight for your oath.
Three, thy now serves Elaine to some capacity, while she need not be your only god, she is the one who provides my power. Therefore by extension, yours.
An oath is not a task to be taken lightly, especially for a mortal, but it is the most rewarding virtue one can achieve.
