Sacrifice

I went through the disgrace of receiving help from Felicia to learn how to use the three stone Tablets. It took quite a while.
But it appears that the place to use the Tablets is none other than the Village of Seethe. As it is swarming with Satyros, I sent an advance unit to clear out the area. I can't go to a place that is dangerous, as you know.
But it angers me that the unit I sent was defeated by those monsters! So you will have to help me here. Go to the <HFFFA7272>Village of Seethe<HFFFFFFFF> and exterminate <HFFFA7272>40 Satyros Deaths<HFFFFFFFF> as well as <HFFFA7272>Sparta<HFFFFFFFF>. I will use these stone Tablets while you are doing that.

Don't get distracted, and just go to the <HFFFA7272>Village of Seethe<HFFFFFFFF> and exterminate <HFFFA7272>40 Satyros Deaths<HFFFFFFFF> as well as <HFFFA7272>Sparta<HFFFFFFFF>.

A door opened in the air when I used the stone Tablets. And I was enraged to find that there wasn't any treasure inside. All I found was some powder in a crystal bottle.
It wasn't what I thought Usus's hoard of treasures might be. So I was going to break it out of anger, and then I noticed something written on the bottle.

What do you think was written on it?
