exile2 coffin caves help please

[Griselda]

I entered "blwlb" at the control panel but I don't think the quest is complete. One of the soul crystals is missing and the other one keeps telling me to go away. Can someone tell me what I'm missing please?

This is it-

However when you go through the river and you go into the council room of the Vahnatai you will be rewarded-

So good job, give yourself a pat on the back and move on to bigger and better things!
