Seal the Potenza

I can assure you as a high-ranking priest that the power contained in this dark stone is from 'Dark Sentio.' I don't know why or how the dead travelers found this, but if this power is left unchecked it may even contaminate our minds.

Fortunately, we have a box that can seal every kind of power. It was created by a sorcerer named La Maz, and it's currently in the <HFFFA7272>Stone of Justice<HFFFFFFFF>. Its original purpose was to seal any matter that may harm the Stone of Justice, you see. Go there and find <HFFFA7272>La Maz's Box<HFFFFFFFF> under the <HFFFA7272>stone plate<HFFFFFFFF>. You must hurry!
You can get to the Stone of Justice by going east from here.

I will say it once again. Go to the <HFFFA7272>Stone of Justice<HFFFFFFFF> and find <HFFFA7272>La Maz's Box<HFFFFFFFF> under the <HFFFA7272>stone plate<HFFFFFFFF> and bring it to me, please. You have to hurry!
You can get to the Stone of Justice by going east from here.

Ah, you brought it. Please give it to me, then. We need it to save this place from chaos!
