To defend your honor, I pledge to thee.
As I kneel before you, on bended knee.
My loyalty to you, until my death,
I’ll fight for you, with my final breath.

No challenge you ask, shall be too great.
To honor you’re bidding without debate,
I decree to you, as a knight of this land,
I’ll do as you ask; I await your command.

I raise my sword, and swear by this troth.
To you and your kingdom, this is my oath.
To forever defend you, until death I do depart.
One Sword, one Knight,
One Heart

Poison 9901
