Creating a Avatar oath

[dragonearth]

SO the point of this thread is basically create the full oath one of the main npc's in my campaign world swore.
How the avatar system works in this world is that once you become one you gain powers that come from the one you swore the oath to.
This character is a paladin of devotion so this makes it not his first. He is all about protecting people and destroying evil.

I already have the shortened base form for the oath as this is what he says to unleash his powers.

I am the shield that defends the light

I am the sword that destroys the darkness

Evils bane, Lights hope

I am Talancar

Please base your ideas around this
Just to let you know the name he was given translates to Hope.
