Well, one could argue that the Vow was blown when Kevin enacted the Desecration, and the Bloodguard (and the whole Haruchai race) not only do not accept failure, but have a very stringent definition of failure. Therefore, I find it completely believable that Korik would recite the Vow on a very regular basis to remind him of that failure, and to insure that it doesn't happen again.Awesome summation F&F - have you ever wondered why there appears to be the need to recite the vow repeatedly?
In fact, you can see that determination not to fail in Bannor's actions in LFB. The Bloodguard have no need for weapons, yet it's Bannor that places TC's ring on the Staff of Law to call the Fire Lions to save the quest (and the Lords, their charges).
Fractional bow to Fist for the excellent post. Fractional bow to Durris who guided me here.
Do not believe that we forget. In all the ages of service, it was the grief of the Bloodguard that they gave no direct battle to Corruption.
